The invention discloses an amine derivative, a preparation method thereof, and an organic light-emitting diode. The general molecular structure of the amine derivative is as follows: or One of, wherein the Ar1 and Ar2 are both aryl groups, the R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15 and R16 All are aryl groups, and the R17, R18, R19 and R20 are all aryl or alkyl groups. The invention combines the characteristics of high hole mobility of thiophene derivatives and high fluorescence properties of furan derivatives, and designs a semiconductor material containing both thiophene functional groups and furan functional groups. The aromatic amine group on thiophene[3,2-b][1]benzofuran can further enhance the hole mobility and luminous efficiency of [1]benzothiophene[3,2-b][1]benzofuran . |
