聚（庚嗪酰亚胺）钾（K-PHI）是一种二维碳氮化物聚合物，最近作为可见光驱动的光催化剂引起了人们的注意。我们开发了一种不需要液体电解质的固体材料，作为K-PHI与离子液体或绝缘聚合物基质的复合材料。所得K-PHI复合材料保留了K-PHI的一些独特的光电性能，并且处于半固态，可以在温暖的状态下容易地成形。使用这些K-PHI复合材料的简单器件通过由白色光照射激活的钾阳离子的离子传导而表现出光电导性。
Potassium poly(heptazine imide) (K-PHI) is a two-dimensional carbon nitride polymer that has recently attracted attention as a visible-light-driven photocatalyst. We developed a solid material that does not require a liquid electrolyte as a composite of K-PHI with an ionic liquid or insulating polymer matrix. The obtained K-PHI composites retained some of the unique optoelectronic properties of K-PHI and were in a semisolid state that could be easily shaped in a warm state. Simple devices using these K-PHI composites exhibited photoconductivity by the ionic conduction of potassium cations activated by white light irradiation.
