Patent ID: 8878169

Claim:
An electronic device comprising a field-effect transistor having a semiconductor layer comprising a semiconducting electronic material, a dielectric layer comprising an insulating electronic material, and source, drain, and gate electrodes each comprising a conducting electronic material, wherein the field-effect transistor comprises: an organic material comprising a crosslinked matrix of a polymer, the polymer comprising a first repeating unit of Formula (Ia) and optionally a second repeating unit of Formula (Ib) that is different from the first repeating unit of Formula (Ia): wherein: L and L′ independently are absent or a divalent linker; W is —(CR a′═CR c′ ) p —(CR b′ ═CR d′ ) p —Z′, Z is selected from the group consisting of a C 1-10 alkyl group, a C 1-10 haloalkyl group, a substituted or unsubstituted C 6-14 aryl group, and a substituted or unsubstituted 5-14 membered heteroaryl group; Z′ is selected from the group consisting of H, a C 1-10 alkyl group, a C 1-10 haloalkyl group, a substituted or unsubstituted C 6-14 aryl group, and a substituted or unsubstituted 5-14 membered heteroaryl group; R 1 and R 2 independently are H or CH 3 ; R a , R a′ , R b and R b′ independently are selected from the group consisting of H, F, Cl, CN, CH 3 , and CF 3 ; R c , R c′ , R d and R d′ independently are selected from the group consisting of H, a C 1-10 alkyl group, a C 1-10 haloalkyl group, a substituted or unsubstituted C 6-14 aryl group, and a substituted or unsubstituted 5-14 membered heteroaryl group; p and p′ independently is 0 or 1; and q and q′ independently is 0 or 1; wherein either the dielectric layer comprises the organic material as the insulating electronic material or the organic material is in contact with at least one of the electronic materials.
