摘要
Abstract We demonstrate a photocatalyst and transition metal catalyst free photo‐activation of quinoxalin‐2(1 H )‐ones in visible light in the presence of an acid catalyst. The photoactivated quinoxalin‐2(1 H )‐one species transfers its energy to oxygen which promotes C−N cross dehydrogenative coupling with nucleophilic partners such as carbazoles, azoles and amides giving the products in 42–75% yields. Preliminary studies reveal quinoxalin‐2(1 H )‐one‐carbazole adducts to display fluorescent properties including Intramolecular Charge Transfer (ICT) and Aggregate Induced Emission (AIE).
