Patent ID: 8039833

Claim:
An electronic device containing a polythiophene wherein R is an alkyl, alkoxyalkyl, a perhaloalkyl, or a polyether; m represents the number of R substituents and is 1 or 2; A is a divalent linkage comprising from about 1 to about 40 carbon atoms; x represents the number of R m substituted thienylene moieties, y represents the number of unsubstituted thienylene moieties, and x and y are each from 1 to 5; z represents the number of divalent linkages A in the monomer segment, z being 0 or 1; n represents the number of repeating monomer segments in the polymer or the degree of polymerization; the device comprises a substrate, a gate electrode, a gate dielectric layer, a source electrode and a drain electrode, and in contact with the source/drain electrodes and the gate dielectric layer a semiconductor layer comprised of said polythiophene; and wherein n is a number of from about 5 to about 5,000.
