| titleOfInvention | Thermally activated delayed fluorescent material based on carbazole and diphenyl sulfone and its preparation method |
| abstract | The invention discloses a thermally activated delayed fluorescent material, which consists of a carbazole or tricarbazole group (R1) with hole transport capability and a diphenylsulfone group (R2) with electron transport capability at the 2-position, 3-position The position or 4-position is connected through a benzene ring; wherein R1 is a carbazole or tricarbazole group, which is substituted at the 1-position of the benzene ring, and R2 is (2-phenylsulfone)phenyl, (3-phenyl Sulfone) phenyl or (4-phenylsulfone) phenyl, substituted at the 3,5-position on the phenyl ring; the thermally activated delayed fluorescent material designed in the present invention has a short synthesis route and a simple synthesis method Easy to operate and suitable for a wide range of applications. The singlet-triplet energy level difference of the material in the invention is less than 0.3 eV, can emit blue light, and can be used as a thermally activated delayed fluorescent blue light material. |
