Phosphonium salt incorporated hypercrosslinked porous polymers for CO2 capture and conversion

Abstract

Various novel hypercrosslinked porous polymers with phosphonium salt incorporated into their networks were developed. These porous materials have high BET surface areas (up to 1168 m² g⁻¹) and can be used to selectively capture CO₂ and efficiently convert CO₂ into cyclic carbonates.
