Abstract:
1. An article comprising, in a thin film transistor, a thin film of organic semiconductor material that comprises a configurationally controlled N,N′-dicycloalkyl-substituted naphthalene-1,4,5,8-bis-carboximide compound having two independently substituted or unsubstituted alicyclic rings each attached to each imide nitrogen with the proviso that at least one of the two alicyclic rings is necessarily a 4-substituted cyclohexyl ring in which a substituent at the 4-position is the sole substituent on the 4-substituted cyclohexyl ring other than the imide nitrogen attachment, wherein said substituent is stereochemically disposed as either an essentially trans or essentially cis position, respectively, to the imide nitrogen substituent.
