Description
Summary:An expanded pyridyl-decorated MOF-505 analogue[Cu 2 (L)(H 2 O) 2 ]·G x (H 4 L = 5,5′-(pyridine-2,5-diyl)diisophthalic acid, G = solvent molecule) has been solvothermally synthesized and reported. It exhibited rare hierarchical meso- and microporosity. With exposed unsaturated Cu II sites and Lewis basic pyridyl sites, the material shows both large CO 2 -uptake capacity (123.4 cm 3 g −1 at 273 K, 1 bar) and high selectivity for CO 2 over N 2 (55.7) at 273 K. Furthermore, for the first time the compound has been exploited for its heterogeneous catalytic performance toward the cyanosilylation reaction under solvent-free conditions. The compound can be recycled up to five times with only a minor loss of activity.
