Claim:
1. A method of fabricating an electronic device comprising a semiconductor layer, the method comprising: forming an organic layer in contact with the semiconductor layer, wherein the organic layer is formed by depositing a thin film from a composition comprising a polymer having the formula: wherein: U and U′, at each occurrence, independently are selected from the group consisting of a halogen, CN, a C W and W′ independently are —Ar[—Y—Ar] Z and Z′ independently are selected from the group consisting of —O—, —S—, and —Se—; L and L′, at each occurrence, independently are selected from the group consisting of —O—, —S—, a divalent C T and T′, at each occurrence, independently are Q or R, wherein: p is 1, 2, 3, 4, 5, 6, 7 or 8; p′ is 0, 1, 2, 3, 4, 5, 6, 7 or 8; x and x′ independently are 0, 1, 2, 3 or 4; m is a real number, wherein 0<m≦1; and n is an integer ranging from 10 to 500; and exposing the thin film to irradiation to photocrosslink the polymer so that the organic layer comprises a photocrosslinked product of the polymer.
