Abstract:
1. An article comprising, in a thin film transistor, a thin film of organic semiconductor material that comprises a heterocycloalkyl-substituted naphthalene tetracarboxylic diimide compound that is represented by the following structure II: wherein, Y is O, S, or N; R 1 , R 2 , R 4 , R 5 , R 2′ , R 4′ , collectively R groups, are each independently H or an organic group, except allowing that optionally any two R groups on a ring system can combine to form a substituted or unsubstituted four to six-membered alicyclic ring as part of a bridged ring system; wherein when Y is O or S, p is 0 and when Y is N, p is 1, and R 3 is H or an organic group; and A 1 is an organic substituent, optionally another independently selected heterocycloalkyl group; and wherein Z is an optional independently selected substituent on the compound's naphthalene nucleus and m is any integer from 0 to 4.
