摘要:

二维共价有机框架(2D COFs)具有拓扑可调性、大比表面积、易于功能化以及出色的稳定性等特性,这些特性使得它们在多相光催化领域中的应用日益广泛。本文首先概述了2D COFs的合成方法,包括溶剂热、离子热、机械化学、微波辅助、声化学和界面合成方法。它简要介绍了影响光催化性能的各种因素,包括结晶度和稳定性、能带结构、电荷转移能力、孔径和比表面积以及光源。随后,讨论转向总结和分析2D COFs作为光催化剂在有机小分子转化反应(如光催化氧化、还原和偶联反应)中的进展。最后,对2D COFs在光催化有机转化领域面临的机遇和挑战进行了总结和展望。

Abstract:

Two-dimensional covalent organic frameworks (2D COFs) exhibit distinctive characteristics, including tunable topology, an extensive specific surface area, susceptibility to functionalization, and robust stability, making them frequently utilizedin multiphase photocatalytic applications. This article begins with an overview of the synthesis methods for 2D COFs, covering solvothermal, ionothermal, mechanochemical, microwave-assisted, sonochemical, and interfacial synthesis techniques. It provides a concise introduction to various factors influencing photocatalytic performance, such as crystallinity and stability, band structure, charge transfer capability, pore size and specific surface area, and the nature of the light source. Subsequently, the discussion shifts to summarizing and analyzing advancements in the use of 2D COFs as photocatalysts for organic small molecule conversion reactions, particularly in photocatalytic oxidation, reduction, and coupling reactions. Finally, summary and outlook are presented regarding the opportunities and challenges that 2D COFs face in photocatalytic organic transformations.
