Abstract

A new class of thermally activated delayed fluorescence (TADF) macrocycles is reported. Among them, cyclic trimers (biphen[3]arenes) based on V-shaped units were synthesized for the first time. And all trimeric macrocycles show macrocyclization-enhanced TADF, where the quantum yield greatly increased from 36.8% to 70.9%.
