Patent ID: 8692238

Claim:
A device comprising an organic semiconductor layer and a single dielectric layer in physical contact with the organic semiconductor layer, the single dielectric layer consisting essentially of an organic film-forming polymer that has a glass transition temperature (T g ) of at least 70° C. and a number average molecular weight (M w ) of at least 20,000, the organic film-forming polymer comprising a backbone comprising at least 0.5 mol % and up to and including 25 mol % of recurring units represented by the following Structure (A), based on total organic film-forming polymer recurring units: wherein X is an organic backbone unit, n is 0 or 1, G is a substituted or unsubstituted divalent organic linking group other than oxyarylene, R 1 is a substituted or unsubstituted aliphatic group comprising at least 6 carbon atoms.
