该研究结果证实了DC-TRZ作为高效深蓝色手性发光体的潜力,imToken钱包,其由二聚咔唑给体与三苯基三嗪受体构成, representing the highest values reported to date for blue CP-OLEDs employing small organic molecules. These results demonstrate that DC-TRZ functions as an efficient deep-blue chiral emitter and highlights C2-symmetric axial chirality as a promising molecular design strategy for high-performance CP-OLED materials.
