A BODIPY‐Based 1D Covalent Organic Framework for Photocatalytic Aerobic Oxidation

Abstract

AbstractCovalent 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 O2 to superoxide anions (O2⋅−) and singlet oxygen (1O2) under visible light irradiation. Benefiting from these properties, JNM‐12 delivered excellent photocatalytic activity in the O2⋅−‐mediated oxidative coupling of amines and 1O2‐engaged aerobic oxidation of enamines. Our work paves a new way for synthesis of COFs as efficient, economical, and green photocatalysts for organic synthesis.
