Graphical Abstract

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 m2 g−1, respectively. It exhibits high gas-uptake capacity for H2 and large adsorption selectivity of CO2 over N2.
