Algorithm deliberately entangles MOFs

Scientists normally want to stop their metal–organic frameworks (MOFs) from interpenetrating. But after realising the drawbacks of these entangled structures could actually be benefits they now want to find ones that definitely will.

It’s hard to mention MOFs without mentioning their pores. These pores and the potential created by their massive surface area have had scientists daydreaming about their possible applications for years. But these pores can easily clog up with sub-lattices, rendering them useless. Or so they thought. Interpenetrated MOFs are very strong and they can still have pores – with a much more specific size, which could be quite handy.

Poster prize winners at CEMWOQ-4

Congratulations to the CrystEngComm poster prize winners who were awarded at The 4th Crystal Engineering and Emerging Materials Workshop of Ontario and Quebec (CEMWOQ-4). The workshop was held in Ontario, Canada from the 26th – 28th May 2017. Christer Aakeroy our Associate Editor attended as a plenary lecturer and was on hand to award the prizes.

The winners were presented accordingly:

1st Place Undergraduate Poster Award: Junghoon Ko, University of Windsor, for “Discotic Liquid Crystals with Internal Side Chains as Potential Organic Semi-Conductors”
2nd Place Graduate Poster Award: Mitchell Nascimento, University of Windsor, for “Expanding the Family of Palladium-DTDA Metal Complexes”
2nd Place Undergraduate Poster Award: Austin Peach, University of Windsor, for “Applications of 35Cl SSNMR for the study of HCl Pharmaceutical Cocrystals”

The workshop enables an easy exchange of ideas, expertise and information and serves as an educational event for students. It also supports/creates new collaborations between research groups. There are plenary and oral presentations, and a poster session with opportunity for discussion within the program. A training workshop on the day before the main meeting is included, on a topic relevant to one or more of the existing themes of the meeting.

Further information on the most recent meeting, and links to other previous meetings, can be viewed at this website.

Solid state synthesis not so solid after all

Weather and climate influence solid state reactions in previously unrealised ways. So say scientists who have found a mysterious liquid phase at the interface between solids when investigating mechanochemical synthesis.

Source: Royal Society of Chemistry Co-grinding a dry mixture of α-glycine and β-malonic acid is known to give a stoichiometric salt, glycinium semi-malonate.

Mechanochemical reactions are performed by grinding two solid reactants together without a solvent. They are often touted as a green alternative to traditional synthesis, and occur via complex pathways quite different to reactions in solution. Humans have used mechanochemistry since time immemorial: to create fire from the friction between two pieces of wood, in the process of ball milling since the industrial revolution, and to prepare powders for pharmaceuticals and rocket propellants.

CrystEngComm Prize winners at the 27th MOSSCS symposium

Congratulations to CrystEngComm prize winners: Bhupinder Sandhu, Yue Qiu and Shane Nichols. They were awarded their prizes at the Midwest Organic Solid State Chemistry Symposium XXVII (MOSSCS) which took place at Kansas State University, USA from the 9th – 10th June 2017. CrystEngComm Associate Editor Christer Aakeroy was on hand to present their certificates.

The MOSSCS symposium provides opportunities for the scientific community to exchange ideas and research results on the organic solid state in a relaxed environment. The symposium involves presentations by graduate students and postdoctoral associates as well as invited lectures on topics of current interest.

Further information about the symposium can be found on their website.

Fractal crystals win fashion design contest

The fractal crystal pattern, transferred onto a dress, won the researchers a prize at a design competition

Organic crystals with never-before-seen curved fractal structures have been discovered by researchers in China. They used the unusual shapes to design a dress, whose striking patterns won a national fashion competition.

Guoqing Zhang, Xuepeng Zhang and their team at the University of Science and Technology of China first intended to construct a series of organic ligands for water-based acrylic paints. By performing a routine Claisen condensation reaction between a ketone and an ester, they obtained a number of pyridine-substituted β-diketone compounds as fluffy crystals, with varying positions of nitrogen-substitution in the pyridine ring.
