Azadiene-Linked Carbon-Organic Frameworks for Enhanced Photocatalytic Efficiency in Organic Synthesis

Abstract

2D covalent organic frameworks (2D-COFs) have garnered huge attention as a promising platform for solar to chemical energy conversion. In this work, two novel azadiene-linked COFs (COF-JLU236 and COF-JLU237) were designed and successfully synthesized under solvothermal conditions for the first time. And new materials have high crystallinity, large surface area, good durability, and broad absorption range, as well as excellent photoelectric properties. Importantly, they can effectively induce selective oxidation of sulfides and phenylboronic acids under visible light, and show wide substrate adaptability and superior reusability.
