Abstract
An organic light emitting material, a preparation method thereof, and an organic light emitting device are provided. The organic light emitting material includes oxadiazole-p-benzodioxazoles. The oxadiazole-p-benzodioxazoles has a large π-conjugated system, that is, it has good planarity and strong visible π-π* absorption. Also, it has high fluorescence quantum yield. Therefore, the oxadiazole-p-benzodioxazoles with a large π-conjugated system has a high-efficiency electron transport property, and it has a high-efficiency electron-withdrawing group to increase electron transport efficiency and improves its luminous efficiency.
