The cycloaddition of CO2 with epoxides to cyclic carbonates is one the most promising and green pathways for utilization, development highly efficient catalysts remains a challenge. In this work, novel hydroxy-rich covalent organic framework (TFPB-DHBD-COF) was synthesized, it served as an heterogeneous catalyst reaction 1,2-epoxybutane under mild conditions, providing desired products in 90% conversion. abundant hydroxy groups pore channels TFPB-DHBD-COF could not only activate via hydrogen bonding but also obviously enhance its stability through intramolecular five-membered ring bonding. Thus, COF exhibited outstanding tolerance diverse substrates. Undoubtedly, work has enriched application tailored COFs activation utilization CO2.
