Abstract: A method is provided for making a thin film transistor comprising the steps of: providing a substrate; applying a gate electrode ink by inkjet printing; applying a dielectric ink over by inkjet printing; applying a semiconductor ink by inkjet printing; and applying a source and drain electrode ink by inkjet printing. In some embodiments the semiconductor ink comprises a solvent and a semiconducting material comprising: 1-99.9% by weight of a polymer; and 0.1-99% by weight of a functionalized pentacene compound as described herein.

Abstract: Briefly, the present invention provides an electronic device, typically a transistor or a capacitor, comprising at least one electrically conductive electrode and, adjacent to the electrode, a dielectric layer; wherein the dielectric layer comprises a polymeric matrix and, dispersed in the polymeric matrix, metal oxide particles; wherein the metal oxide particles have organic functional groups covalently bound to their surface, and wherein the organic functional groups are not covalently bound to the polymeric matrix. In another aspect, the present invention provides a printable dispersion, typically a jet-printable dispersion, comprising: a) a curable composition and b) metal oxide particles; wherein the metal oxide particles have organic functional groups covalently bound to their surface, and wherein the organic functional groups are not covalently bound to any part of the curable composition.
