A thermally activated delayed fluorescence material and a synthesis method therefor, the general formula for the chemical structure of the material being as follows: A, B, C, and D are all structural groups in the material, and x, y, and z are respectively molar ratios which groups B, C, and D account for in the material. Polystyrene is used as a main chain, and side chains are connected to red, green, and blue light-emitting structural units to synthesize a white light polymer material having high light-emitting efficiency; an OLED light-emitting layer prepared by using the described material has a high service life and good light-emitting performance. |
