CrystEngComm video cover trial

Have you seen the video cover from CrystEngComm

Illustrating the work published in their CrystEngComm article, Bergström et al. provide us with an overview of the growth process of self-assembled mesocrystals and ordered arrays from iron oxide nanocubes. By using visible light video microscopy, the authors were able to follow the movement of the growth crystal growth front over several minutes, capturing the transition from symmetrical “coffee-ring” deposition to dendritic or “finger-like” growth. The article forms part of the ‘Nanocrystal growth via oriented attachment’ themed issue which is available here

In a first for both CrystEngComm and the Royal Society of Chemistry, a short video clip of the crystal growth has been embedded into the journal cover which you can access online here. To view the video, simply click on the main cover image and watch the cover come to life!* Adobe Acrobat 9 or higher is required (http://get.adobe.com/reader/). If the video does not play in your browser, try downloading it and opening it in Adobe Acrobat on your desktop.  

We’re on the look-out for innovative ways to showcase research so do not hesitate to get in touch if you have a video or animated graphics to help tell the story of your published CrystEngComm article. 

We’ve been experimenting with some other engaging ways of adding the authors’ video to both the cover and the article.

Video on the article landing page

We’ve added the full version of the video to the article landing page here, where it appears below the traditional abstract text and image. To enable us to embed the video we uploaded it to our YouTube channel, RSC Journals, which has the added benefit of making it available to people looking for chemistry videos on YouTube.

Video on your tablet or smartphone

You can also watch the full video on your tablet or smartphone using a free augmented reality app called Junaio Augmented Reality Browser. To do this you’ll need a tablet or phone that’s connected to the internet and has a camera on the back.

To watch the video:

•              Use you app store of choice to install Junaio.

•              Get the cover image ready to scan. You can open the article pdf from here to the first page on your computer screen, print the first page (this will work for both colour and greyscale printing), or just scan the image in this blog post.

•              Open the Junaio app, position your phone or tablet so that the cover image is on the screen, and press the scan button in the top right corner of the screen.

•              The Royal Society of Chemistry logo will appear briefly in the top left corner, indicating that you have connected to our channel, and then the YouTube video page will be displayed.

•              Press play and enjoy the video.

One of the nice things about the augmented reality version is that the video is associated with the image, not just the cover, which makes it quite versatile. For example, the authors could use the image (without the play button and the journal branding) on a conference poster and people with a suitable phone or tablet would also be able to scan it and watch the video.

Please do have a look and let us know what you think in the comments. Which versions are good and which could be better? What are your favourite features and why? Is there anything else you would like to see?

For more information about the science behind the video, read the free-to-access CrystEngComm article using the link below and watch the video on the article landing page.

Making drug delivery containers with bubbles

Successful use of pharmaceutical drugs depends on their delivery and controlled release so that their bioactivity can be harnessed.  This can mediate poor solubility, degradation and other properties of the drug which might otherwise be problematic.  One way to control delivery is to load the drug into a container which allows the compound to be transported to the desired location, to then be released over a suitable time period.  The behaviour of the container is dependent on both the size and the shape, so simple and reliable fabrication techniques are required.

In a recent CrystEngComm article, scientists from China show how such containers can be made which are shaped like lotus leaves and are nano/microsized.  The Co3O4 nano/microcontainers can be easily prepared from Co(NO3)2.6H2O by evaporation of the acetone solvent followed by calcining (i.e. heating at below the melting point).   In this process, shown in the diagram below, the large amount of gas bubbles produced are key to determining the shape of the containers, with no other shape-directing agents required.  The size and density of the nano/microlotus-leaf arrays can be controlled by variation of the evaporation time and temperature.

Fabrication of Co3O4 lotus-leaf shaped containers

The research team used fluorescein isothiocyanate (FITC) as a model drug to study the controlled drug delivery from the nano/microlotus-leaf arrays.  They found that it could be loaded and released more effectively than for comparable Co3O4 microspheres and showed that cells which were treated with the arrays retained over 80% viability even at high concentration — indicating that these microcontainers are a safe delivery vehicle of active compounds to cells.

For more details, see the paper:

Jumping Crystals

Posted on behalf of Josh Campbell, web writer for CrystEngComm 

The phenomenon of jumping crystals was first reported in 1983 when it was discovered that heating crystals of (phenylazophenyl)palladiumhexafluoroacetylacetonate caused not only a polymorphic transition, but also the sample to literally “jump” off the heat source.  Since then, mechanically responsive materials research has blossomed due to potential applications in medical devices, actuators and electronic sensors. Most research in the field has focussed on molecular scale movement (typically using rotaxanes or catenanes) or light-activated polymers for macroscopic movement. However, single crystals possess many of the properties needed for practical applications of actuators.  The ordered structure of the crystal should allow any induced effect to travel faster which allows faster energy transfer, shorter response times and faster recovery. 

Light- and heat-induced mechanical effects in single crystalsA new highlight article in CrystEngComm recaps some of the recent progress in the field, focusing on the mechanical processes seen in thermo- and photo-responsive crystals. Thermally induced jumping is known as the thermosalient effect and has been reported for many materials. Crystals that exhibit this effect generally fall into three types: crystals which contain hydrogen bonds; crystals without hydrogen bonding groups that form stacked layers; and crystals with no strong intermolecular interactions whatsoever. For the second class, the ability of a layered structure to exhibit hopping depends on the interactions between layers and the thermal motion of the atoms between them. Oxitropium bromide is one such crystalline material, which undergoes a reversible conformational change which has the effect of loading, and then decompressing, a spring. For polar molecules, a compression along the most polar axis can lead to mechanical effects. 

Photo-responsive crystals rely on the photochromic effect, a reversible transformation that occurs on the absorption of electromagnetic radiation. Crystals can respond mechanically to this absorption with a range of mechanical effects. For example, microcrystals of trans-4-aminoazobenzene bend away from UV light. Bending and curling is often seen with cis–trans isomerism, ring opening and closure and cycloaddition reactions. The photosalient effect has also been reported, whereby mechanical strain develops in the crystal due to a photochemical reaction. An example of this is α-santonin, its crystals turn yellow and burst when exposed to sunlight. 

Research into thermal and photo induced mechanical effects is now picking up compared to previous decades after the realisation of their importance in both energy conversion and for developing mechanically responsive materials.

CrystEngComm Editor’s choice

In this Editor’s choice post, Professor Christer Aakeröy, Associate Editor for CrystEngComm, talks about his favourite articles published in the journal in recent months. Christer has chosen the most interesting articles in the area of molecular recognition crystal engineering.  


Deprotonation of resorcinarenes by mono- and diamine bases: Complexation and intermolecular interactions in the solid state
N. Kodiah Beyeh,   Arto Valkonen and  Kari Rissanen 
CrystEngComm, 2013, DOI: 10.1039/C3CE42291G    

Structural chemistry investigations of macrocyclic compounds such as calixarenes and resorcinarenes are frequently hampered due to problems with crystal growth, and it is quite rare that a successful structural study is supported and complemented by solution- and gas-phase data.  Rissanen and co-workers have produced a systematic and comprehensive exploration of several deprotonated alkyl-resorcinarenes which offers a broad perspective of the structural and chemical behavior of representatives of a ‘classic’ supramolecular system.  The single-crystal studies indicate that the deprotonated macrocycles act as effective hosts for the protonated amines in the solid state and the acid-base behavior in solution is monitored by NMR titrations.  The deprotonated resorcinarenes (monomer and dimer) were observed using EI mass spectrometry in negative ion mode while the 1:1 and 2:1 complexes with the protonated guests were observed in positive ion mode in the gas phase.

Can self-assembly of copper(II) picolinamide building blocks be controlled?
Marijana Đaković, Diogo Vila-Viçosa, Nuno A. G. Bandeira, Maria José Calhorda, Bojan Kozlevčar, Zvonko Jagličić and Zora Popović 
CrystEngComm, 2013, 15, 8074-8087   

In this paper, Đaković et al examine the structural role played by picolinamide ligands in the directed assembly of a series of Cu(II) based complexes.   The study is supported by an impressive range of experimental and theoretical tools, and offers a comprehensive analysis and evaluation of an important aspect of crystal engineering.    The authors have examined the precise role that different factors play in the assembly of each structural motif and the outcome is a much enhanced understanding of the templating effect of the metal ion as well as of the complementarity of non-covalent interactions.  Finally, the structural work is supported by careful magnetic measurements the results of which are subsequently properly interpreted and rationalized using DFT-based calculations.

Knowledge-based hydrogen bond prediction and the synthesis of salts and cocrystals of the anti-malarial drug pyrimethamine with various drug and GRAS molecules
Amit Delori, Peter T. A. Galek, Elna Pidcock, Mohit Patni and William Jones 
CrystEngComm, 2013,15, 2916-2928   

The ability to determine which primary intermolecular interactions are most likely to take place given the presence of certain functional groups is of key importance in crystal engineering.  In this study, the authors adopt a knowledge-based approach that takes full advantage of the unique structural information that is provided within the Cambridge Structural Database.  Through the use of hydrogen bond propensity calculations (HBPC), which perform a statistical analysis of the occurrence of specific hydrogen bonds among structures of relevant molecules, it is possible to estimate which hydrogen bonds are most likely to take place between different molecules.   Different hydrogen bonds are assigned propensity scores which provides an avenue for predicting of co-crystals are likely to form between two different molecules and, if so, the type of intermolecular interactions that can be expected within the heteromeric co-crystal.  HBPC calculations were utilized to predict the likelihood of forming co-crystals between the anti-malarial drug pyrimethamine and carbamazepine, theophylline, aspirin, α-ketoglutaric acid, saccharin, coumaric acid, succinimide and L-isoleucine.  The HBPC agreed with the experimental observations indicating that this approach may offer effective and versatile tools for finding new solid forms of high-value chemicals such as pharmaceuticals and agrochemicals.

Complexities of mechanochemistry: elucidation of processes occurring in mechanical activators via implementation of a simple organic system
Adam A. L. Michalchuk, Ivan A. Tumanov and Elena V. Boldyreva 
CrystEngComm, 2013,15, 6403-6412   

Mechanochemistry is a current ‘hot topic’ which is of considerable interest to both covalent and supramolecular synthetic chemists.  A wide range of chemical transformations are now known to be possible using essentially ‘green’ reaction conditions.  Arguably, most papers that have presented in this field focus on proof-of-principle studies which demonstrate that “functional group ‘A’ can be converted to ‘B’ using the following reaction conditions”, but mechanistic or kinetic studies are still relatively uncommon.  In this paper, however,  Michalchuk et al, present a very detailed examination of the α-glycine : b-malonic acid system which include an analysis of how two key mechanical ‘forces’ – impact and shear – can influence reaction paths and product distribution.  This study clearly demonstrate that what actually happens in a ball mill or through a mortar-pestle treatment is likely to be far more complicated than what is assumed in most studies, notable the role played by the actual mechanoreactor itself.  The results are likely to be of critical importance to many mechanochemical reactions especially in the context of scale-up.

Synthon identification in co-crystals and polymorphs with IR spectroscopy. Primary amides as a case study
Arijit Mukherjee, Srinu Tothadi, Shaunak Chakraborty, Somnath Ganguly and Gautam R. Desiraju 
CrystEngComm, 2013, 15, 4640-4654

It is probably fair to say that many crystal engineering efforts rely far too heavily on the use of single-crystal X-ray diffraction for product analysis and/or for interpreting the outcome of a particular crystallization or supramolecular synthesis.  However, in this paper, Desiraju and co-workers present a careful and informative study that correlates crystallography with vibrational spectroscopy.  In order to overcome the well-known challenges when using IR spectroscopy for analyzing polymorphs and co-crystals containing multiple synthons, the authors have employed a four-step approach that relies on the use of ‘spectral markers’ that can be directly associated with bonds in specific synthons.  The method is tested on an acid–phenol–pyridine co-crystal system and subsequently utilized for correctly identifying the different synthons in polymorphs of isonicotinamide.

Halogen bond directionality translates tecton geometry into self-assembled architecture geometry
Marco Saccone, Gabriella Cavallo, Pierangelo Metrangolo, Andrea Pace, Ivana Pibiri, Tullio Pilati, Giuseppe Resnati and Giancarlo Terraneo 
CrystEngComm, 2013,15, 3102-3105 

This paper offers a particularly well-planned and carefully executed strategy for supramolecular synthesis.  One some level, this study may seem overly simplistic and the results may appear to be ‘obvious’ but this is, in my opinion, a testament to the progress that has been made in this field.  We sometimes forget that non-covalent synthesis has to rely on relatively weak and reversible interactions in an environment where solvent molecules are more than capable of disrupting solute-solute biding and, furthermore, that recrystallization is generally favored over heteromeric co-crystallizations.  The fact that we may think that the results presented herein are unsurprising simply means that we are making considerable progress towards finding and developing supramolecular reactions that display a robustness and reliability that we typically associate with named reactions in organic synthesis. 

Halogen bonds.

Drug-drug co-crystals of anti-inflammatory agent, FFA

Flufenamic acid (FFA) is a potent non-steroidal anti-inflammatory drug used to treat lower back pain, either orally or topically.  However, it has low solubility and a slow dissolution rate which are problematic.  One way these properties can be improved is by forming a solid solution with polyvinylpyrrolidine or a co-crystal with nicotinamide (NA).  Co-crystals form between the active molecule and a co-former and possess different physicochemical properties from either of the components.

A recent CrystEngComm article reports the formation and X-ray structures of three new co-crystals of FFA, with the co-formers theophylline (TP), 4-pyridone and 4,4’-bipyridine.  Each of the three structures shows the formation of heterosynthons (i.e. interactions between complementary functional groups) e.g. for FFA-TP, interactions between FFA O-H and TP N atoms.   TP is a central nervous system stimulant, found in cocoa beans, and used to treat respiratory diseases such as asthma.  The FFA-TP system is an example of a drug-drug co-crystal, where both components have biological activity and therefore is of particular interest.

The authors found improved solubility and dissolution rate for this system, compared to either pure FFA or the FFA-NA co-crystal.  They also compared the properties to a TP co-crystal with oxalic acid, with the FFA-TP co-crystal proving less hygroscopic.

FFA co-crystals

These results suggest that formation of this co-crystal offers improved properties for both FFA and TP and in addition, offers an opportunity to explore the development of combination drugs by forming drug-drug co-crystals.

We will also participate in a global experiment for school children involving crystals. Keep an eye out for more information about the symposium and the global experiment as they develop.

In 2013 a number of people joined our Editorial Board, bringing with them expertise and experience of their particular research fields. Joining Editorial Board Chair, Len MacGillivray (University of Iowa, USA), Associate Editors Rahul Banerjee (CSIR-National Chemical Laboratory, India) and Christer Aakeröy (Kansas State University, USA) and Board member Nicola Pinna (Humboldt-Universität zu Berlin, Germany) are Associate Editors Hongjie Zhang (Changchun Institute of Applied Chemistry, China) and Georg Garnweitner (TU Braunschweig, Germany) and Board members Graeme Day (University of Southampton, UK), Tomislav Friščić (McGill University, Canada), Michaele Hardie (University of Leeds, UK), Helmut Cölfen (Universitat Konstanz, Germany) and Pierangelo Metrangolo (Politecnico di Milano, Italy). We very much look forward to our collaborations with them all.

The way we connect with our friends, peers and colleagues is changing, and social media is an important tool for this. CrystEngComm is no different. We have a number of outlets for CrystEngComm via social media, expanding the ways in which people can get involved with the journal. The journal has a Facebook page and Twitter account (why not join our 1000 followers?) and our LinkedIn group is a good way to learn about relevant conferences and other news. Our latest offering is our ‘Crystal Clear’ Pinterest page, illustrating some of the stunning crystal images that are included in the journal.

Fiona McKenzie (Deputy Editor) and I will be attending two conferences in 2014: the Crystal Engineering Gordon Research Conference and the IUCr meeting. An important related meeting is the Faraday Discussion meeting 170 with a focus on Mechanochemistry: From Functional Solids to Single Molecules. The meeting will be in Montreal, Canada in May, and more details are available via www.rsc.org/ConferencesAndEvents/RSCConferences/FD/FD170/index.asp

We were very pleased to support a number of international conferences in 2013 through sponsorship. We also provide support via poster prizes – in 2013, we awarded 10 poster prizes, celebrating the achievements of members of our community in the early years of their academic careers. If you are organising a conference in 2014 and you would like us to sponsor a poster prize, please let us know.

Let us connect you and your work into the world’s leading chemistry community in 2014, the International Year of Crystallography: publish with CrystEngComm!

Have a fantastic 2014!
