ORGANIC SEMICONDUCTOR CONTAINING ACETYLENIC ANTHRACENE, AND ORGANIC THIN FILM TRANSISTOR USING THE SAME

摘要

An organic semiconductor compound, and an organic thin film transistor(TFT) containing the compound are provided to improve charge mobility and on/off ratio and to reduce leakage current. An organic semiconductor compound is represented by the formula 1, wherein A1 and A2 are independently C, Si or Ge; and R1, R2, R3 and R4 are independently H, a linear, branched or cyclic C1-C30 alkyl group, a linear, branched or cyclic C2-C40 alkenyl group, a linear, branched or cyclic C3-C40 alkynyl group, a linear, branched or cyclic C1-C30 alkoxy group, a C6-C40 aryl group, a C4-C30 heteroaryl group, a C6-C30 ar(C1-C30)alkyl group, a C1-C30 alkoxy(C1-C30)alkyl group, a C1-C30 alkoxy(C2-C30)alkenyl group, a C6-C50 heteroaryl(C1-C30)alkyl group, a C1-C40 carbyl group, a hydro(C1-C40)carbyl group, a C6-C40 aryloxy group, a C1-C40 alkoxycarbonyl group, a C6-C40 aryloxycarbonyl group, a cyano group, a carbamoyl group, a haloformyl group, a formyl group, an isocyano group, an isocyanate group, a thiocyanate group, a thioisocyanate group, a mono or di(C1-C30)alkylamino group, a mono or di(C6-C30)arylamino group, a hydroxyl group, a halogen atom, a nitro group, or a silyl group, or can be crosslinked with the carbon atom of the adjacent anthracene ring to form a C1-C30 saturated or unsaturated ring.
