多组分反应作为一种强大的一锅组合合成手段，近年来被广泛应用于共价有机骨架的合成。与热驱动的mcr相比，光催化mcr合成COF的研究尚未开展。在此，我们首次报道了用光催化多组分反应构建COFs。在可见光照射下，通过光氧化还原催化的多组分Petasis反应，在常温条件下成功合成了一系列结晶度、稳定性和永久孔隙度优异的COFs。此外，所得Cy-N3-COF具有良好的光活性和可回收性，可用于芳基硼酸的可见光氧化羟基化反应。光催化多组分聚合的概念不仅丰富了COF合成的方法，而且为现有基于热驱动mcr的合成方法所无法实现的COF的构建开辟了新的途径。
Multicomponent reactions (MCRs), as a powerful one-pot combinatorial synthesis tool, have been recently applied to the synthesis of covalent organic frameworks (COFs). Compared with the thermally driven MCRs, the photocatalytic MCR-based COF synthesis has not yet been investigated. Herein, we first report the construction of COFs by a photocatalytic multicomponent reaction. Upon visible-light irradiation, a series of COFs with excellent crystallinity, stability, and permanent porosity are successfully synthesized via photoredox-catalyzed multicomponent Petasis reaction under ambient conditions. Additionally, the obtained Cy-N3-COF exhibits excellent photoactivity and recyclability for the visible-light-driven oxidative hydroxylation of arylboronic acids. The concept of photocatalytic multicomponent polymerization not only enriches the methodology for COF synthesis but also opens a new avenue for the construction of COFs that might not be possible with the existing synthetic methods based on thermally driven MCRs.
