Abstract

The Front Cover illustrates the micro-environments associated with photocatalytic cross-dehydrogenative coupling (CDC) reactions, wherein covalent organic frameworks (COFs) function as heterogeneous catalysts. COFs exhibit favorable photocatalytic activity in diverse chemical transformations, owing to their remarkable high crystallinity, excellent stability, and convenient recyclability. The CDC reactions represent an efficient and clean methodology for the formation of C-Nu (Nu = nucleophilic reagent) bonds through activation of C-H and Nu-H bonds, respectively. As expected, the robust COFs offer a highly versatile platform for heterogeneous photocatalytic CDC reactions. More information can be found in the Concept article by Bin Guo, David J. Young, Hong-Xi Li, and co-workers (DOI: 10.1002/cptc.202400274).

封面：基于共价有机框架（COF）的光催化交叉脱氢偶联反应催化剂（ChemPhotoChem 2/2025）

前封面说明了与光催化交叉脱氢偶联（CDC）反应相关的微环境，其中共价有机框架（COFs）作为多相催化剂。COFs具有较高的结晶度、优异的稳定性和方便的可回收性，在多种化学转化中表现出良好的光催化活性。CDC反应分别通过活化C-H和Nu- h键形成C-Nu （Nu =亲核试剂）键，是一种高效、干净的方法。正如预期的那样，强大的COFs为非均相光催化CDC反应提供了一个高度通用的平台。更多信息可以在郭斌、David J. Young、李洪喜及其同事的概念文章中找到（DOI: 10.1002/cptc.202400274）。
