Triazine-Based Conjugated Microporous Polymers for Efficient Hydrogen Production

Developing visible-light-active porous organic polymers with high photocatalytic efficiency is highly desirable. Here, two triazine-based conjugated microporous polymers were synthesized. The structures were controllably adjusted to explore the structure-photocatalytic activity relationship. T-CMP-1 containing more triazine units exhibited a hydrogen evolution rate of 3214.3 μmol h^-1 g^-1, much higher than that of T-CMP-2 (242.1 μmol h^-1 g^-1). The increasing contents of triazine units bring better hydrogen evolution efficiency.
