An organic light-emitting material, a method for the preparation thereof and use thereof are provided. The organic light-emitting material is a novel organic light-emitting material containing phosphine, has a high electron-transport property and a high fluorescence quantum efficiency, can be used as an emitting layer material and/or an electron transport layer material in an OLED element. Thus, an emitting layer and an electron transport layer in a traditional OLED element can be combined as one layer, thereby simplifying the structure and preparation process of the OLED element. Also, the organic light-emitting material has a specific response to oxygen, metal ions, etc., so that the organic light-emitting material can also be applied in the fields of chemo-biological detection, bio-imaging, anti-counterfeiting, etc. There are advantages of simple synthesis and purification, high yield, and adjustment of its luminous wavelength, luminous efficiency, etc. by introducing different functional groups. |
