 This study investigates the development of a novel multiple donor acceptor, DA, type organic light emitting diode, OLED, material with two distinct donor units of 9, 10, dihydro, 9, 9, dimethylacridine, DMAC, and carbazole. The results show that this multiple DA type emitter has higher photoluminous quantum yield, PLQY, compared to single DA type emitters. Furthermore, the multiple DA type emitter shows improved photo stability and operational stability in OLEDs. This work demonstrates the potential of multiple DA type emitters for developing more efficient and stable TADF materials.
