In this study, a novel porous metal–organic framework (MOF) functionalized with amino and triazole moieties has been synthesized. Attributed to the high affinity to CO₂ and unsaturated zinc centers, the MOF exhibits high catalytic activity for the CO₂ to epoxide cycloaddition reaction, with a turnover number value of up to 10 000 per cycle, and can be reused at least for 20 cycles.
