A polycyclic heteraborin multiple resonance thermally activated delayed fluorescent scaffolds (NO-DBMR and Cz-DBMR) based on role-play with HOMO energy to achieve the extremely narrow FWHM of 14 nm were proposed and synthesized via lithium free one-shot double borylation. The organic light emitting diode employing the NO-DBMR/Cz-DBMR manifested state-of-the-art performance with high color purity and external quantum efficiency of 29.8/33.7 %.
