We report an organic photocatalytic system, namely 3,3′,5,5′-tetra- tert -butyl-4,4′-diphenoquinone (DPQ) and air, capable of coupling efficiently with the photocyclization of stilbenes to afford phenacenes. The potential of this new and mild process is shown with the synthesis of [5]- and [7]phenacene, two semiconductors recently implemented into organic electronic devices, with high yields and remarkable
我们报告了一种有机光催化体系,即 3,3',5,5'-四叔丁基-4,4'-二苯醌 (DPQ) 和空气,能够与芪的光环化有效偶联以提供非苯。[5]-和[7]非苯这两种半导体最近用于有机电子器件中,具有高产率和显着的纯度,显示了这种新的温和工艺的潜力。
