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 .
