  铑（III）催化的酚类化合物邻-杂芳基化通过内部氧化Ç ？H活化：单分子白光发射材料的快速筛选

  摘要：

  本文报道的是过渡金属催化的内部氧化CH / C的第一个例子通过无痕氧化引导策略在两个（杂）芳烃之间进行H交叉偶联。在不需要外部金属氧化剂的情况下，各种各样的酚（包括含酚的天然产物）可以与唑类偶联，从而组装出一个高度官能化的2-（2-羟基苯基）唑类大型文库。该路线为快速筛选发白光的材料提供了机会。作为说明性的例子，两个双（三苯胺）的2-（2-羟基苯基）恶唑类化合物很难获得，它们显示出明亮的白光发射，高量子产率和热稳定性。还呈现白色光发射的第一例中，在一个单一的激发态分子内质子转移系统，2-（2-羟基苯基）吡咯，从而突出C的魅力在新的有机光电子材料的发现中进行H活化。
