Capture of carbon dioxide by conjugated microporous polymers

Towards the global efforts to reduce carbon emission, carbon dioxide capture is currently being investigated as a potential strategy towards this goal.

Conjugated microporous polymers (CMPs) as a sub-family of microporous organic polymers (MOPs) are good candidates for CO2 capture because of the wide-ranging flexibility in the choice and design of components and the available control of pore parameters.

Dr Renqiang Yang and his colleagues (researchers at Chinese Academy of Science, University of Chinese Academy of Science and Taiwan National Central University) designed and synthesized three phospine oxide-based microporous polymers TEPO 1-3 owning strong affinity for CO2. The effects of the rigid length and fuctionalization of the monomer skeleton on the performance of porous materials has been investigated. Although the BET (Brunauer-Emmett-Teller) surface area of the TEPOs are less than 600 m2 g-1, the three polymers exhibit relatively high sorption abilities for CO2 (8.40 wt%) and ultrahigh hydrogen uptake (1.02 wt% at 77K/1.0 bar) compared to materials with similar BET surface areas. Interestingly, the polymers obtained exhibit remarkable performance in separating CO2 over CH4 as the selectivity of CO2/CH4 is a high as 15.5 at 273K.

This work reveals clearly that the gas uptake capacity of materials is highly depending on the length of rigid skeleton and the modification of functional groups in the monomer structure.

Congratulations to the NJC Poster Prize winner at ISXB-1

NJC was pleased to honour Alavi Karim from the University of Gothenburg (Sweden) for her outstanding poster presentation at the 1st International Symposium on Halogen Bonding (ISXB-1) that was held in Porto Cesareo (Italy) on June 18–22.

Alavi Karim is a graduate student in the Department of Chemistry and Molecular Biology where she works under the supervision of Dr. Mate Erdelyi. Her project currently focuses on Understanding Halogen Bonding in Solution.

In her award-winning poster titled “The Nature of [N–Cl–N]+ and [N–F–N]+ Halogen Bonds in Solution” she presented solution-phase NMR spectroscopy data and theoretical studies investigating the geometries and stabilities of the highly reactive, lighter haloniums in comparison to their well-studied iodonium and bromonium centered analogues. Alavi said: “We have characterized three-centre-four-electron halogen bonds, [N–X–N]+, in solution and demonstrated the iodine-, bromine- and chlorine-centred halogen bonds to be static symmetric. In line with fluorine, the [N+–F···N] system shows different behaviour in comparison to the heavier halogens. The complex is asymmetric and thus encompasses one conventional-covalent and one conventional-weak halogen bond. The fluorine- and chlorine-centred systems are highly reactive and could therefore only be stabilized in solution at low temperature. The conclusions drawn from NMR studies were supported by DFT calculations.”

The poster prize committee and winner (from left to right): Giuseppe Resnati, Francesca Baldelli-Bombelli, Alavi Karim and Pierangelo Metrangolo.

Many congratulations to Alavi on receiving her NJC poster prize. She also received a book from the Royal Society of Chemistry and a 1-year electronic subscription to New Journal of Chemistry.

Fluorescent carbon dots from office waste printer paper

Professor Boxue Feng and his co-workers from Lanzhou University in China present a creative idea for the recycling of waste paper.

In their NJC Letter, they report a simple synthesis of water-soluble, fluorescent carbon dots (CDs) from waste paper as the carbon source via hydrothermal process at 180°C. They showed that the as-prepared CDs exhibit strong luminescence properties, good photostability, high photoluminescence quantum yield and fairly low toxicity. The green method described in this study indicates the potential applications of such prepared CDs in the field of bio-imaging.

Meet Our Authors – November Issue 2013

by Ling PENG, NJC Assistant Editor

Here is a selection of author profiles from the 2013 November issue of NJC. We thank them most warmly for accepting our invitation and having kindly taken their time to answer a few questions for us.


Our first author is Dr. Jean-Pierre Majoral, who is currently an emerita Research Director of exceptional grade in CNRS. He is interested in all aspects of dendrimer properties and applications from biology to medicinal chemistry, material sciences and catalysis. His contribution to this issue is a concise review which presents not only the “state of the art” concerning the use of dendrimers as tools to tackle different aggressive types of cancers (from colon to brain ) but also to point out what should be (or will be) done using dendrimers to face important remaining challenges encountered by medicinal chemists. “It is difficult for me to imagine a different career than the one I had and currently I have!” says Jean-Pierre with a total satisfaction working as a researcher during all a career.  
Prof. Larry Que is a Regents Professor of Chemistry at University of Minnesota, and focuses mainly on bioinorganic chemistry. In this issue, he contributed a paper entitled “Cyclohexene as a versatile substrate probe for the nature of the high-valent iron-oxo oxidant in bio-inspired nonheme iron-catalyzed oxidations”.  “I love discovering new, unusually reactive compounds and understanding how they work. I also enjoy training young scientists very much” claimed Prof Que.  
Prof. Michio Yamada is an Assistant Professor at Tokyo Gakugei University. He is interested in the chemistry of carbon-rich architectures such as fullerenes, carbon nanotubes, and acetylene scaffolds. Currently, he is pursuing the structure-based design and synthesis of novel molecular receptors to explore the supramolecular chemistry of nanocarbons. In his contribution to this issue, he reported a new method for functionalization of fullerenes using photolabelling reagents. “If I couldn’t be a chemist, I’d be a curator in a museum of natural history. Actually I spent a lot of time in museums with my parents in my childhood and the experience was valuable and unforgettable”, says Prof. Yamada.  
Prof. Clotilde Policar is specialized in bio-inorganic chemistry and cellular inorganic chemistry and working at Ecole Normale Supérieure in Paris. She contributed an article entitled “An Intrinsically Fluorescent Glycoligand for Direct Imaging of Ligand Trafficking in Artificial and Living Cell Systems” in the October issue of NJC.  For her, the most exciting moment is “when a difficulty vanishes, at any level; from a simple technical problem solved to a deeper understanding of a phenomenon. It can be after a long process or in a short moment of insight. It is always enlightening and produces a deep joy and emotion that is, to me, the quintessence of research.”

Meet Our Authors – August Issue 2013

Two authors of NJC’s August issue are interviewed for this month’s Meet our Authors feature.

Our first author is Dr. Faina Gelman, who is researcher at the Institute of Geological Survey of Israel, The Hebrew University of Jerusalem. Her current research interests are environmental chemistry and stable isotope analysis. She particularly focuses on development of new analytical tools for stable isotope analysis and their applications for understanding chemical and biochemical transformations of organic compounds.

In their NJC paper, Faina with her colleagues demonstrated determination of bromine kinetic isotope effect on Grignard reagent formation –one of the fundamental reactions of brominated organics. ” Since our work combines novel analytical, theoretical and organic chemistry approaches, we wanted to submit it to a more general-focused journal, such as NJC is, from our point of view” commented on choosing NJC.

And what contemporary scientific issue is she most concerned about: “I am very much concerned about environmental pollution and would like to find an efficient way to treat this problem “she replied. Besides her research activity, Faina likes to spend time with her family.

Bromine kinetic isotope effects: insight into Grignard reagent formation by Lukasz Szatkowski, Agnieszka Dybala-Defratyka, Charlie Batarseh, Jochanan Blum, Ludwik Halicz and Faina Gelman ; New J. Chem., 2013, 37, 2241-2244; DOI: 10.1039/C3NJ00197K.

The second author is Jürg Hulliger, who is a Professor of chemistry at the University of Berne, Switzerland. His research interest centers on Crystal growth, properties and solid state theory. His contribution to this month’s issue is Focus article that reviews on polar properties of solid molecular matter.”Here we review basic theoretical views on growth induced polarity in molecular crystals giving also all known experimental examples we have by today, which domonstrate polarity Formation. ”

If Jürg could solve any scientific problem, it would be: “Constructing equipment being able to say : a small Crystal of the size of a few 100 nm is (i) superconductive, (ii) is composed of these elements and (iii) shows this crystal structure. Such an Equipment may be used to analyze your combinatorial ceramic samples.”

In the non-lab world, Jürg is fascinated by interior decoration in the style of the 18th century, renovation of antics and art.

A stochastic principle behind polar properties of condensed molecular matter by Jürg Hulliger, Thomas Wüst, Khadidja Brahimi, Matthias Burgener and Hanane Aboulfadl  New J. Chem., 2013, 37, 2229-2235 DOI: 10.1039/C3NJ40935J

We thanks to Faina and Jürg for accepting our invitation to talk about themselves and their work!

NJC poster prize at 5th ECCLS

We are delighted to present the recent poster prizes awarded at the 5th European Conference on “Chemistry for Life Sciences” (5th ECCLS) in Barcelona, that gathers an ensemble of scientists at the crossroads between chemistry, biology, biophysics and material science.

Two young scientists Montserrat Serra-Batiste and Sven Hofmann received NJC Poster Prizes that reward creative and multidisciplinary research works in the chemical sciences.

Montserrat Serra-Batiste is a postdoctoral researcher in the group of the Prof. Ernest Giralt at the Institute for Research in Biomedicine, Barcelona (Spain) working under the supervision of Dr. Natàlia Carulla since September 2010.

Montserrat’s winning poster dealt with well-defined Aß42 oligomers in a biomimetic membrane environment. The idea project started with the idea of Dr Natàlia Carulla of stabilizing Aß oligomers by using an environment similar to what this peptide have in vivo. Different conditions have been testing by different techniques in order to get a stable and homogeneous preparation of Aß oligomers. As a result, an Aß42 hexamer (named (Aß42)6Membrane) has been stabilized which adopts extensive ß-sheet secondary structure and exhibits specific Aß42-Aß42 interactions. Preparation of (Aß42)6Membrane should open the possibility to explore more in deep the role of Aß oligomers in Alzheimer’s disease.

Her future plans include working with Natàlia to characterize the structure and the biological relevance of this Aß42 hexamer and contribute in solving the puzzle of Alzheimer’s disease. Besides research activities Montserrat loves cooking and dancing.

The award-winning poster of Sven Hofmann was entitledCarbaboranes in Short Neuropeptide Y Analogs – Redirecting BiologicalActivity”. Carbaboranes are icosahedral boron-carbon clusters mimicking phenyl rings. In particular, they present a three-dimensional hydrophobic structure and are capable of providing a special type of hydrogen bonding, the so-called proton-hydride bonding. Their unique chemical properties are perfectly suited for improving the biological activity of small bioactive molecules but also of peptide analogs.

Sven is a graduate student working in the research group of Prof. Annette G. Beck-Sickinger at the University of Leipzig, Leipzig (Germany) since October 2010. Working in the field of chemical modification of peptides to gain receptor subtype selectivity and biological stability, he especially focuses on the synthesis of short functionalized peptide ligands as selective diagnostic and therapeutic tools.

His future plans are not fixed yet. However, he will finish his Ph.D. in 2014 and he will apply for a postdoctoral research position abroad. Outside of the lab, Sven’s favorite activities are running, cycling, athletic sport challenges and travelling.

The two laureates received a one-year subscription to the journal and a RSC book. Our thanks go to the organizers of the conference for their help in organizing these awards, and our deep gratitude to all of the senior scientists who served on the jury to select the two following winners:

NJC wishes them continuing success in their research!
