Covalent organic frameworks (COFs) as metal-free photocatalysts have attracted extensive interest. However, the organic transformations photocatalyzed by COFs under mild conditions remain a challenge. Herein, a boron-dipyrromethene (BODIPY) based 1D COF, namely JNM-12, was facilely constructed by Schiff-base condensation reaction. JNM-12 exhibited strong visible-light harvesting abilities and suitable photocatalysis energy potentials, enabling the activation of O to superoxide anions (O ⋅ ) and singlet oxygen ( O ) under visible light irradiation. Benefiting from these properties, JNM-12 delivered excellent photocatalytic activity in the O ⋅ -mediated oxidative coupling of amines and O -engaged aerobic oxidation of enamines. Our work paves a new way for synthesis of COFs as efficient, economical, and green photocatalysts for organic synthesis.
共价有机框架(COFs)作为无金属光催化剂引起了广泛关注。然而,在温和条件下 COFs 催化的有机转化仍然是一个挑战。在此,通过席夫碱缩合反应简便地构建了一种基于硼二吡咯甲烷(BODIPY)的 1D COF,即 JNM-12。JNM-12 表现出较强的可见光吸收能力和适宜的光催化能量势,可在可见光照射下将 O 激活为超氧阴离子(O ⋅ )和单线态氧( O )。得益于这些特性,JNM-12 在 O ⋅ 介导的胺的氧化偶联和 O 参与的烯胺的有氧氧化反应中表现出优异的光催化活性。我们的工作为合成 COFs 作为高效、经济和绿色的有机合成光催化剂开辟了新途径。
