Abstract:
The present invention is drawn to a thin-film transistor having a layer of semiconducting organic material provided on an insulating substrate and integrated with at least two electrical contacts for applying an electric voltage to the semiconducting organic material, wherein the semiconducting organic material is a semiconducting organic random copolymer with a highly ordered chain structure, a large effective conjugation length and a high regioregularity, and wherein the copolymer is synthesized from different fractions of at least two organic monomer compounds, with the smallest of the at least two monomer compounds being present in the lowest fraction.
