I19-Small Molecule Single Crystal Diffraction	A chiral, self-catenating and porous metal-organic framework and its post-synthetic metal-uptake Michaele J. Hardie , Tia Jacobs , Rob Clowes , Andrew Cooper Angewandte Chemie International Edition 51 (21), 5192-5195 DOI: 10.1002/anie.201200758 PMID: 22488777 Diamond Proposal Number(s): [7180] Show Abstract ▼ Abstract: Free vacancies: A robust and porous metal–organic framework material with unique 4-connected self-catenating structure of {85⋅10} topology was synthesized. The structure features empty bipyridine metal-chelating sites that can be doped with copper cations in a single-crystal-to-single-crystal post-synthetic modification (see picture; scale bar 20 μm).

Cooper , Chiu Tang , Stephen Thompson Nature Materials DOI: 10.1038/nmat2545 Show Abstract ▼ Abstract: Porous materials are important in a wide range of applications including molecular separations and catalysis. We demonstrate that covalently bonded organic cages can assemble into crystalline microporous materials. The porosity is prefabricated and intrinsic to the molecular cage structure, as opposed to being formed by non-covalent self-assembly of non-porous sub-units. The three-dimensional connectivity between the cage windows is controlled by varying the chemical functionality such that either non-porous or permanently porous assemblies can be produced. Surface areas and gas uptakes for the latter exceed comparable molecular solids. One of the cages can be converted by recrystallization to produce either porous or non-porous polymorphs with apparent Brunauer–Emmett–Teller surface areas of 550 and 23 m2 g-1, respectively. These results suggest design principles for responsive porous organic solids and for the modular construction of extended materials from prefabricated molecular pores.	Oct 2009
