Layered Thiazolo[5,4-d] Thiazole-Linked Conjugated Microporous Polymers with Heteroatonn Adoption for Efficient Photocatalysis Application

Conjugated microporous polymers (CMPs) with high surface areas, tunable building blocks, and fully conjugated structures have found important applications in optoelectronics. Here, we report a new series of CMPs with tunable band gaps by introducing thiazolo[5,4-d] thiazole as the linkage. Because they are synthetic polymers, the geometries and structures could be rationally designed. Their intrinsic wide visible-light absorption properties and layered architectures endow them with a promising photocatalytic performance. The role of geometries, surface areas, and morphologies of the CMPs in photo-catalysis abilities is examined and discussed. The results indicate that geometries have a direct impact on the surface areas and morphologies of the CMPs and thus exert great influence on photocatalysis.
