Abstract
Abstract The intrinsic helical π‐conjugated skeleton makes helicenes highly promising for circularly polarized electroluminescence (CPEL). Generally, carbon helicenes undergo low external quantum efficiency (EQE), while the incorporation of a multi‐resonance thermally activated delayed fluorescence (MR‐TADF) BN structure has led to an improvement. However, the reported B,N‐embedded helicenes all show low electroluminescence dissymmetry factors ( g EL ), typically around 1×10 −3 . Therefore, the development of B,N‐embedded helicenes with both a high EQE and g EL value is crucial for achieving highly efficient CPEL. Herein, a facile approach to synthesize B,N‐embedded hetero[9]helicenes, BN[9]H , is presented.…
