Abstract

Two diazaborepins (BNN1 and BNN2) have been accomplished via a highly efficient pathway in the step-economic transformation. Oxidative dimerization of carbazole derivatives followed by borylation reaction gave heterocyclic diazaborepin as the key building block. Replacement of carbon moiety in traditional borepins with N-N functionality led to a significant red shift of their emissions up to 585 nm with strong red color as solids. This work offered an approach to diazaborepin-based materials for applications in light-emitting field.
