Synergistic performance of a sub-nanoscopic cobalt and imidazole grafted porous organic polymer for CO2 fixation to cyclic carbonates under ambient pressure without a co-catalyst

Abstract

A facile, single-step development strategy of a sub-nanoscopic Lewis acidic Co and basic imidazole grafted porous organic polymer is reported. The synergistic activation of an epoxide and CO₂ by the Lewis pairs present in the material manifested their rapid conversion to cyclic carbonates under ambient pressure with high yield, selectivity, and TOF.
