Abstract

Abstract: New BN‐heterocyclic compounds have been found to undergo double arene photoelimination, forming rare yellow fluorescent BN‐pyrenes that contain two BN units. Most significant is the discovery that the double arene elimination can also be driven by excitons generated electrically within electroluminescent (EL) devices, enabling the in situ solid‐state conversion of BN‐heterocycles to BN‐pyrenes and the use of BN‐pyrenes as emitters for EL devices. The in situ exciton‐driven elimination (EDE) phenomenon has also been observed for other BN‐heterocycles. Abstract : Arene elimination reactions of BN‐heterocycles (A ) in an electroluminescent device result in the in situ formation of BN‐pyrenes (B ) and BN‐phenanthrenes. This is a novel approach to the creation of functional EL devices.
