Patent ID: 8513654

Claim:
A compound for an organic thin film transistor having a structure shown by the following formula (1): X 1 -L-Ar-L-X 2 (1) wherein L is —C≡C—, or —CH═CH— in a trans configuration, X 1 and X 2 are independently an alkyl group having 2 to 30 carbon atoms or a haloalkyl group having 1 to 30 carbon atoms, and Ar is a substituted or unsubstituted aromatic hydrocarbon group having 14 to 60 ring carbon atoms which is a condensed ring of three or more rings, or a substituted or unsubstituted aromatic heterocyclic group having 11 to 60 ring atoms which is a condensed ring of three or more rings, and wherein the substituents of the aromatic hydrocarbon group and the aromatic heterocyclic group are selected from the group consisting of a halogen atom, a cyano group, a haloalkyl group having 1 to 30 carbon atoms, a haloalkoxy group having 1 to 30 carbon atoms and a haloalkysulfonyl group having 1 to 30 carbon atoms.
