A green and sustainable catalytic system was developed based on perylenediimide (PDI) organic semiconductor for the aerobic oxidative hydroxylation of arylboronic acids in aqueous solution with visible light. By using PDI-SN, a hydrophilic organic semiconductor, which can activate oxygen to produce superoxide radicals in aqueous solution, this reaction proceeds under ambient conditions: water as the solvent and air as the oxidant, giving various phenols as products with high yields. In contrast to methods using organic solvents, this novel process has the potential of green industrial application.

亲水性有机半导体在可见光促进水中芳基硼酸的好氧氧化羟基化

开发了一种基于（二酰亚胺（PDI）有机半导体的绿色可持续催化体系，用于可见光下水溶液中芳基硼酸的好氧氧化羟基化。通过使用PDI-SN（一种亲水性有机半导体，可以活化氧在水溶液中产生超氧自由基），该反应在环境条件下进行：以水为溶剂，以空气为氧化剂，以高收率得到各种酚。与使用有机溶剂的方法相比，这种新颖的方法具有绿色工业应用的潜力。
