Patent ID: 7745821

Claim:
An article comprising, in a thin film transistor, a thin film of organic semiconductor material that comprises one or more aryl dicarboxylic diimidazole-based compounds selected from the group consisting of compounds represented by the following structures: wherein Ar 1 and Ar 2 are the same or different, and are each carbocyclic or heterocyclic aromatic ring systems, comprising 4 to 60 carbon atoms, fused to each corresponding adjacent imidazole in the structure, wherein each of Ar 1 , and Ar 2 are substituted with at least one or more fluorine atoms, and X is an optional organic or inorganic substituent group at any available position on the core nucleus; n is zero or an integer from 1 to 8 and m is zero or an integer from 1 to 4, wherein the thin film transistor further comprises first and second contact means in spaced apart contact with the thin film and third contact means spaced apart from the organic semiconductor material.
