Photocurable Polymeric Materials and Related Electronic Devices

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 —(CRa′═CRc′)p—(CRb′═CRd′)p—Z′,
• Z is selected from the group consisting of a C1-10 alkyl group, a C1-10 haloalkyl group, a substituted or unsubstituted C6-14 aryl group, and a substituted or unsubstituted 5-14 membered heteroaryl group;
• Z′ is selected from the group consisting of H, a C1-10 alkyl group, a C1-10 haloalkyl group, a substituted or unsubstituted C6-14 aryl group, and a substituted or unsubstituted 5-14 membered heteroaryl group;
• R1 and R2 independently are H or CH3;
• Ra, Ra′, Rb and Rb′ independently are selected from the group consisting of H, F, Cl, CN, CH3, and CF3;
• Rc, Rc′, Rd and Rd′ independently are selected from the group consisting of H, a C1-10 alkyl group, a C1-10 haloalkyl group, a substituted or unsubstituted C6-14 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.
