Summary: In this study, porous organic polymers (POPs) with diverse quaternary phosphonium units were synthesized and used as catalysts for cycloaddition reaction of CO2 and epoxides. The POPs exhibited excellent catalytic properties even under mild conditions and without the need for a co-catalyst. The catalytic activities of the POPs were found to increase with the steric hindrance of the quaternary phosphonium units.

Summary: Our study reveals a new mechanism for CO2 fixation onto cyclic carbonates, which differs from the commonly accepted mechanism with alternate epoxide and CO2 activation steps and a nested CO2 activation pathway. The general applicability of this mechanism was demonstrated through reactions catalyzed by two different catalysts.

Summary: This study developed a facile method for preparing hydrogen bond donors functionalized porous ionic polymers using free-radical polymerization and HBDs functionalization reactions. Among the synthesized bifunctional PIPs, the catalyst with carboxyl groups showed better catalytic performance in CO2 cycloaddition compared to the one with hydroxyl groups, and the HBDs-free catalyst exhibited the lowest activity. The catalyst with carboxyl groups demonstrated high catalytic activity, excellent reusability, and broad substrate tolerance under atmospheric CO2 pressure and co-catalyst free conditions.

Summary: Several multifunctional histidine-based hypercrosslinked ionic polymers (HIPs) were synthesized via a one-pot copolymerization strategy, and their CO2 adsorption and conversion properties were investigated. The HIPs exhibited hierarchical pore structure and incorporated abundant hydrogen bond donors, nucleophilic ionic sites, and Lewis bases. The optimized HIP-Br-His showed a high CO2 capture capacity and excellent catalytic activity in the cycloaddition of CO2 to propylene oxide, highlighting its potential as a heterogeneous catalyst for efficient CO2 capture and conversion.

Summary: Efficient, green, and recyclable heterogeneous catalysts for the conversion of CO2 into cyclic carbonates under atmospheric pressure conditions are challenging to develop. In this study, rosin-based porous heterogeneous catalysts MPAc-Br and MPAc-OH-Br were synthesized and the bifunctional catalyst MPAc-OH-Br showed higher catalytic activity (up to 99% yields) for CO2 conversion. The catalyst exhibited good stability and reusability, making it a promising candidate for sustainable CO2 conversion processes.
