A semiconductor material, a preparation method for same, and an application. A general formula of a molecular structure of the semiconductor material is one of aa-gg, where Ar1 and Ar2 are an alkyl group or an aryl group, Ar3, Ar4, Ar5, and Ar6 are an aryl group, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16 are an aryl group, and R17, R18, R19, and R20 are an aryl group or an alkyl group. The characteristics of a thiophene derivative having higher carrier mobility and a furan derivative having better fluorescence properties are combined in the present invention, so as to design the semiconductor material comprising both a thiophene functional group and a furan functional group, thereby resolving the issue in existing organic semiconductor materials of being unable to have at the same time both high carrier mobility and high fluorescence efficiency. |
