Abstract

Presented here is a chiral microporous metal–organic framework material with a three-fold interpenetrating diamond-type structural topology and interesting properties for selective separation. The material has a high storage capacity for CO2 gas (4.23 mmol g−1 at 273 K and 1 bar) and shows fantastic temperature-dependent selectivity for CO2 over N2. Moreover, this multifunctional material, which has a rich π system, can selectively adsorb benzene over cyclohexane at low pressure (0.05 bar) at 298 K.
