摘要

一种基于蒽基共价有机框架（COF）锚定Pd(0)纳米粒子（Pd/AntCOF）光催化水中芳基溴化物和芳基硼酸的Suzuki-Miyaura交叉偶联。AntCOF既稳定了Pd(0)纳米粒子，又作为可见光催化剂分离电子和空穴，促进了底物的氧化加成和金属转化。在没有蓝光照射的情况下，只获得了微量的产物。该方案具有广泛的官能团耐受性，并且在四个循环后，多相光催化剂的活性损失可以忽略不计。

Anthracene-based covalent organic framework supported palladium nanoparticles for visible-light-mediated Suzuki–Miyaura cross-coupling†

An anthracene-based covalent organic framework (COF) anchoring Pd(0) nanoparticles (Pd/AntCOF) photocatalyzed Suzuki–Miyaura cross-coupling of arylbromides and arylboronic acids in water under blue LED irradiation at ambient temperature. The AntCOF both stabilized the Pd(0) nanoparticles and acted as a visible-light photocatalyst to separate electrons and holes, facilitating oxidative addition and transmetallation of the substrates. Only a trace of product was achieved without blue light irradiation. This protocol exhibited wide functional group tolerance and the heterogeneous photocatalyst could be recycled with negligible loss of activity after four cycles.
