Abstract
This application relates to an electroluminescent polymer based on phenanthroimidazole units and its preparation and use. 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; (2) the phenanthroimidazole unit has a large degree of conjugation and a strong rigidity; and (3) the raw materials of the polymer are cheap, the synthetic route is simple, and purification is convenient. 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.
