A collection of papers in memory of Lord Jack Lewis

17 Feb 2015

We are very pleased to announce the launch of a commemorative article collection in memory of Lord Jack Lewis.

Lord Jack Lewis, who recently died aged 86, was the 1970 Inorganic Professor at Cambridge for 25 years from 1970 to 1995. Highly energetic and extremely talented, he was among a small band of pioneers who revolutionised inorganic chemistry and must be regarded as one of the true founding fathers of the modern field. As a tribute to Jack, Brian F. G. Johnson, William. P. Griffith, Robin J. H. Clark, John Evans, Brian H. Robinson and Paul R. Raithby have chosen a selection of his papers that they feel demonstrate Jack’s interest and contribution to inorganic chemistry over the course of his career, introducing them in a special Editorial in Dalton Transactions.

We very much hope that you will enjoy this commemorative article collection.

To access all of the Lewis articles and the Editorial, go to: http://rsc.li/lewis.

Bridging the gap – small ligands in MOFs

06 Feb 2015

In a recent article from the group of Deanna D’Alessandro at the the University of Sydney, Australia, Liang et al. have shown for the first time a 3D metal-organic framework (MOF) comprised solely of the monocarboxylate ligand derived from formic acid, with exceptionally selective CO₂ adsorption properties.

For those involved in MOF chemistry, it is well accepted that in most cases, organic bridging ligands should have at least two coordinating functional groups that link adjacent inorganic secondary building units into a porous crystalline lattice. Therefore, it comes as a complete surprise to find that a porous MOF can be formed entirely of monocarboxylate ligands that are traditionally used to cap and thus prevent further growth of the framework. Through structural characterisation, Liang et al. have shown that the formate takes on two different binding modes within the framework; one that caps the oxyzirconium cluster secondary building units, and another that bridges and interconnects these into a crystalline architecture.

Why is this important, I hear you ask? As the formate ligands are very small, this results in the formation of very small pores that can lead to selectivity in the adsorption of different gases. This is just what has been shown by Liang et al., with adsorption isotherms demonstrating that adsorption of CO₂ is a factor of 145 higher than for N₂. Potential applications may lead to the sequestration and use of greenhouses gases such as CO₂ from the atmosphere.

Christopher Hinde obtained his Masters degree in Chemistry from the University of Southampton, UK in 2011. He is currently doing research towards a Ph.D. in the area of materials chemistry and catalysis under the supervision of both Dr Robert Raja at the University of Southampton and Professor T. S. Andy Hor at the Institute of Materials Research and Engineering (IMRE), part of Singapore’s Agency for Science Technology and Research (A*STAR).
