| titleOfInvention | Polymer electron transfer material, preparation method thereof, and organic electroluminescent device |
| abstract | The invention belongs to the field of organic semiconductors, and discloses a polymer electron transfer material, a preparation method thereof and an organic electroluminescent device. The structural general formula of the above host material is shown in the specification. In the formula, R is a C1-C20 alkyl group, and n is an integer from 10 to 92. In the polymer electron transfer material, fluorene is a planar biphenyl structure, and the structure has large rigidity, so the fluorene structure has high thermal stability, and 9-position is modified with carbazole to improve the hole transport performance and the triplet energy level of the fluorene; and thiofluorene contains electron-withdrawing S=O, and is an excellent electron transfer unit, and 4-position and 8-position can be modified through alkyl groups to improve the dissolving performance and the film forming performance of the polymer, so the efficiency of the organic electroluminescent device based on the polymer is improved. |
