design of an asymmetric covalent triazine framework as an efficient organic single‐component semiconductor photocatalyst. Four different molecular donor–acceptor domains are obtained within the network, leading to enhanced photogenerated charge separation via an intramolecular energy transfer cascade. The photocatalytic efficiency of the asymmetric covalent triazine framework is superior to that of
可以构建复杂的多组分半导体光催化剂,该催化剂通过多次电荷和能量转移表现出增强的催化效率,从而模仿自然界中的光系统。相反,单组分半导体光催化剂的效率通常由于光生激子的快速重组而受到限制。在这里,我们报告了一种不对称共价三嗪骨架的设计,该骨架是一种有效的有机单组分半导体光催化剂。在网络中获得了四个不同的分子供体-受体域,从而通过分子内能量转移级联增强了光生电荷的分离。不对称共价三嗪骨架的光催化效率优于其对称对应物。
