Abstract

A novel yellow-orange thermally activated delayed fluorescence emitter with an asymmetric, high-orientation and rigid molecular structure is reported. This emitter simultaneously achieves a high photoluminescence quantum yield of 80% and an excellent horizontal dipole ratio of 91%, enabling an OLED with a maximum external quantum efficiency of 26.4%.
