摘要

共轭微孔聚合物（CMPs）由于在气体吸附与分离、能量存储、化学传感、多相催化和光催化水分解制氢领域的良好应用前景而广受关注。本文通过Suzuki偶联反应制备了两种含硫共轭微孔聚合物，研究了聚合物中所含基团的电负性对聚合物的光物理性能和可见光光催化水分解制氢性能的影响。研究表明，合成的两种含硫CMPs具有相似的表面形貌和微孔结构，但其能带间隙不同。将其进行可见光光催化水分解制氢测试，两者均具有光催化效果，其中含二苯并噻吩砜基团的SCMP-1产氢效率更高，达到194

Abstract

Conjugated microporous polymers (CMPs) are attracting increasing attention due to their potential applications in areas such as gas adsorption

separation

energy storage

chemical sensing

heterogeneous catalysis and photocatalysis. Two sulphur-containing CMPs have been synthesized via Pd-catalyzed Suzuki coupling reaction. The two CMPs show high chemical stability

high thermal stability

high degree of microporosity

decent specific surface areas and appropriate optical band gaps for photocatalytic hydrogen evolution. Photocatalytic water-splitting hydrogen evolution rates of the CMPs were studied and they could both produce hydrogen under visible light irradiation. SCMP-1 exhibits higher hydrogen evolution rate of 194

under visible light (
