A thermally activated delayed fluorescent material, a synthesis method, an OLED light-emitting device, and a display device, the general chemical structure formula of the thermally activated delayed fluorescent material is: Wherein, A, B, C, and D are all structural groups in the polymer material, and x, y, and z are respectively the proportions of the group B, the group C, and the group D in the polymer material. molar ratio. By using polystyrene as the main chain and connecting red, green, and blue light-emitting structural units with side chains, a white light-emitting polymer material with high luminous efficiency is synthesized; the OLED light-emitting layer prepared by using this material has high life and good Luminous properties. |
