Abstract: Disclosed are an electroluminescent polymer based on phenanthroimidazole units, a preparation method therefor, and the use thereof. The electroluminescent polymer based on phenanthroimidazole units has a structure as shown in the formula (I), and the side chain thereof contains phenanthroimidazole units. The electroluminescent polymer (1) has the properties of hybridized local and charge-transfer states, which can improve the utilization of excitons and the electroluminescence properties of devices by means of reverse inter-system crossing to effectively utilize triplet state excitons; (2) the phenanthroimidazole unit has a large degree of conjugation and a strong rigidity, which can not only improve the thermal stability of a material, but can also increase the radiation transition rate of the material and improve the light-emitting efficiency thereof; and (3) the raw materials of the polymer are cheap, the synthetic route is simple, and purification is convenient, which is beneficial for industrial scaled-up production thereof. The polymer has a good solubility, and can be used to prepare large-area flexible display devices by means of a solution processing technology. The polymer has great development potential and prospects in the field of organic electronic display.
