Carbazole-based DABNA analogs (CzDABNAs) were synthesized from triarylamine by regioselective one-shot single and double borylation. The reaction proceeded selectively at the ortho position of the carbazolyl group, where the HOMO is mainly localized owing to the difference in the electron-donating abilities of the diarylamino and carbazolyl groups. The facile and scalable method enabled synthesis of CzDABNAs, exhibiting narrow-band thermally activated delayed fluorescence with emission spectra ranging from deep blue to green. The organic light-emitting diode devices employing these products as emitters exhibited deep-blue, sky-blue, and green emission with high external quantum efficiencies of 19.5, 21.8, and 26.7%, resp.
