Abstract

A TADF emitter with hybrid short- and long-range charge-transfer excited states is designed by grafting a triazatruxene donor onto a multi-resonance framework. The emitter exhibits narrowband deep-blue emission with enhanced photophysical properties and enables efficient deep-blue electroluminescence.
