| titleOfInvention | A small organic blue light molecule based on phenanthroimidazole and its application in the preparation of undoped organic electroluminescent devices |
| abstract | An organic blue light small molecule based on phenanthroimidazole and its application in preparing non-doped organic electroluminescence devices belong to the technical field of organic optoelectronic materials. In the present invention, the rigid structure phenanthroimidazole is connected with a neutral group or a weak acceptor group in a reasonable manner, so that the excited state of the molecule has the characteristic of a weak charge transfer state, which is beneficial to improve the color purity of blue light emission. At the same time, the substituents introduced on the phenanthroimidazole have a certain steric hindrance to inhibit the interaction between molecules, which can alleviate the mutual quenching process between molecules to a certain extent. The phenanthroimidazole derivatives possess bipolar transport properties, excellent thermal and chemical stability. The non-doped electroluminescence device prepared by using the derivative has the advantages of low turn-on, low roll-off, high efficiency, high color purity, etc., and can promote the further development of organic electroluminescence. |
