Patent ID: 7579619

Claim:
An article comprising, in a thin film transistor, a thin film of organic semiconductor material that comprises an N,N′-di(arylalkyl)-substituted naphthalene tetracarboxylic diimide compound having a substituted or unsubstituted carbocyclic aromatic ring system attached to each imide nitrogen atom through a divalent hydrocarbon group, wherein substituents, if any, on each carbocyclic aromatic ring system are independently selected electron donating organic substituents, wherein said compound is represented by the following structure: wherein, X is a —CH 2 — or alkyl substituted —CH 2 — divalent group, m is 0, n is 2 or 3, and wherein in said structure all of R 1 , R 3 , R 4 , R 5 , R 6 , R 8 , R 9 , and R 10 are H, and at least one of R 2 and R 7 is an alkyl group.
