Abstract

Fused twin-acridine scaffolds of TMQAC and MeTMQAC were designed as novel donors to construct new organic emitters. TMQAC-based emitters were TADF active, while the TADF character was turned off in MeTMQAC-based emitters by the extra methyl group. The TMQAC-based emitters exhibited high OLED performances, with external quantum efficiencies (EQEs) of up to 20.7%.
