摘要：

Picky cage: A dicopper(II)-paddle-wheel-based metal-organic framework (PCN-80, see picture) with a rare (3,3,4)-connected topology has been synthesized by using a unique octatopic ligand featuring 90° bridging-angle dicarboxylate moieties. PCN-80 has Brunauer-Emmett-Teller (BET) and Langmuir surface areas of 3850 and 4150 m 2 g -1, respectively. It exhibits high gas-uptake capacity for H 2 and large adsorption selectivity of CO 2 over N 2. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
