文摘

Novel and functional conjugated microporous polymers (PCMPs) with pyridine units in networks were synthesized from arylethynylenes and 2,6-bis(bromomethyl) pyridine by palladium-catalyzed Sonogashira–Hagihara crosscoupling chemistry. The resulting PCMPs exhibit good chemical and thermal stability with decomposition temperature above 400 °C. The choice of ethynyl monomer has an obvious influence on the specific surface areas of the resulting CMPs. A high BET surface area of 1136 m² g^− 1 was achieved. Taking advantages of the good physicochemical stability and excellent porosity, the functional CMPs networks show superior adsorption performance for CO₂ with uptake up to 109.0 mg g^− 1. Given the excellent porosity and gas uptake as well as good physiochemical stability, the as-synthesized PCMPs show great potentials in CO₂ uptake. Our study may provide fundamental guidance in designing new CMPs-based materials for the application in CO₂ capture and storage.
