Hot Highlight: Porphyrinic metal organic frameworks

07 Mar 2012

Three types of possible pillaring present in porphyrin paddlewheel frameworks using a 4,4'-bipyridine ligand

Metal-organic frameworks (MOFs) are a hot topic of research in crystal engineering given the range of potential applications, including catalysis, gas storage and sensing. The construction of the crystalline materials is very important to determine the properties of the material and this is controlled by careful selection of linkers (organic molecules) and joints (metal ions or clusters).

Porphyrins provide a versatile choice of linker as they can accommodate a range of transition metals and main group elements, this allows metals to be introduced into the frameworks without the need for them to also act as joints, making the metal ions more accessible and increasing interaction with guest molecules.

Schematic illustration of a metal–organic framework, assembled from metal nodes and metalloligands

Porphyrin based MOFs have been reported by Robson, Goldberg, Suslick, Li, Choe, Hupp, Ma and others, this Hot Highlight by Brandon Burnett, Paul Barron and Wonyoung Choe reviews the recent advances in porphyrinic MOFs, focussing on materials design, synthetic strategies and emerging applications.

2012 Gordon Research Conference on Crystal Engineering

07 Mar 2012

The 2012 Gordon Research Conference on Crystal Engineering will be held in the Waterville Valley Resort, New Hampshire, USA from 10–15^th June 2012.

The conference is chaired by Robin D. Rogers alongside CrystEngComm Associate Editor, Christer Aakeröy and Mike Zaworotko who are vice chairing). Sessions will include Nucleation, Crystal Growth, and Solid State Reactivity; Polymorphism and Crystal Structure Prediction; and Catalysis in Porous Materials. Susan Bourne (University of Cape Town), Lee Cronin (University of Glasgow), Pierangelo Metrangolo (Politecnico di Milano) and Gautam Desiraju (Indian Institute of Science) have been invited to speak. Read my recent interview with Professor Desiraju here…

There will be a Crystal Engineering Gordon Research Seminar before the conference on 9–10^th June, focusing on the design, synthesis, and applications of metal–organic materials and coordination polymers. These seminars are a forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new ideas. The deadline for registration for this seminar is 12^th May 2012.

The application deadline for the conference is 13^th May 2012. CrystEngComm Deputy Editor, Fiona McKenzie, is planning to attend and would love to meet you there if you are too – please let her know.

March Crystal Clear: Crystal Snowflakes

06 Mar 2012

This month’s Crystal Clear shows crystals which look remarkably like snowflakes!

FESEM image of dendritic PbTe nano-crystals

In fact this is an image of three-dimensional PbTe dendrites, taken using field emission scanning electron microscopy (FESEM). The paper, published in Issue 6 of CrystEngComm, details the fabrication of these crystals in the presence of β-cyclodextrin.

Gang Chen et al. of the Harbin Institute of Technology have developed a facile synthesis to control the morphology of the nano-crystals. Lead telluride is a typical IV–VI semiconductor and controlling the size and shape of the material has initiated substantial interest. Nano-cubes, nano-octahedrons, nano-wires, nano-rods and hopper crystals have been synthesised as well as flower-like and dendritic structures.

These dendritic crystals have been successfully synthesized via a facile, rapid solvothermal process in the presence of β-cyclodextrin. The authors have characterised the products and propose a mechanism of formation for the crystals and the influencing parameters.

To read more about their developments you can download the article now, which is free to access for 4 weeks.
