Organic light-emitting material, preparation method therefor, and organic light-emitting device |
| abstract |
Disclosed are an organic light-emitting material and a preparation method therefor, and an organic light-emitting device. The organic light-emitting material comprises oxadiazole-p-benzodioxazole. According to the organic light-emitting material and the preparation method therefor, and the organic light-emitting device of the present invention, the organic light-emitting material contains oxadiazole-p-benzodioxazole, which entails good planarity and a high visible π-π* absorption capacity, as well as a fluorescence emission capability with high quantum yields. As a result, the oxadiazole-p-benzodioxazole with a large π-conjugated system has efficient electron transport characteristics. As an efficient electron withdrawing group, the oxadiazole-p-benzodioxazole can increase the efficiency of charge transfer and effectively improve the luminous efficiency of organic light-emitting devices. |
