Au-Acyclic Diaminocarbene-Linked Porphyrin Covalent Organic Framework as a Cascade Catalyst for Photocatalytic Sulfide Oxidation and Intermolecular Nucleophilic Addition

The design and synthesis of a multifunctional covalent organic framework (COF) for various applications have been considered a big challenge. Herein, we report the construction of a novel porphyrin-based Au-acyclic diaminocarbene (Au-ADC)-linked COF (abbreviated as <b>Au-ADC-Por-COF</b>) via a metal-mediated nucleophilic addition reaction. The resultant multifunctional <b>Au-ADC-Por-COF</b> revealed an outstanding performance in a cascade catalyzing photocatalytic sulfide oxidation under visible-light irradiation and intermolecular nucleophilic addition. This research might open a new way for the design of advanced materials with unprecedented structures and catalytic activities.
