Herein, we report two topology\u2010engineered heteroaromatic emitters, BO\u2010DPAB3 and BO\u2010DPAB4. Through precise modulation of the number, ratio, and spatial arrangement of B, N, and O heteroatoms, a twisted \u03c0\u2010conjugated framework with finely tuned electronic structure was constructed. The controllable multi\u2010boron \u03c0\u2010extension enables multidirectional electron delocalization while preserving localized excited\u2010state characteristics. The rigid twisted topology minimizes structural relaxation and weakens intermolecular interactions, thereby reducing aggregation\u2010caused quenching and enabling narrowband deep\u2010blue emission at 453 and 449\u00a0nm with a full\u2010width at half\u2010maximum (FWHM) of 24 and 20\u00a0nm, respectively. Notably, organic light\u2010emitting diode (OLED) devices based on the symmetric tetraboron emitter BO\u2010DPAB4 achieve a maximum external quantum efficiency (EQE\n                    <jats:sub>max<\/jats:sub>\n                    ) of 30.1% and a Commission Internationale de l\u2019\u00c9clairage (CIE) coordinate of (0.138, 0.073).
