One Molecular Platform, Three Distinct Narrowband Organoboron TADF Emitters: A Divergent One‐Pot Strategy From Green to Red

Angewandte Chemie, EarlyView.
One platform–three emitters: Divergent one‐pot borylation of a single indolocarbazole platform exploits competing mono‐ and double‐borylation pathways to generate three spectrally distinct organoboron MR‐TADF emitters spanning green to red, enabling color‐tunable narrowband OLEDs with external quantum efficiencies over 30%.
