Abstract
The cycloaddition reaction of carbon dioxide (CO2) is a highly economic solution to becoming carbon-neutral. Herein, we have designed and synthesized a robust zinc(II)-organic framework (Zn-Ade-TCPE) by a function-directed strategy. Zn-Ade-TCPE possesses uncommon hexagonal cages with Lewis acid-base bifunctional sites and displays a high adsorption capacity for CO2. At room temperature and atmospheric pressure, Zn-Ade-TCPE exhibits outstanding activity, selectivity, and recyclability in the cycloaddition reaction of epoxides with CO2 because of the synergistic effect of multiple active sites and confined cavities.
