Abstract:
1. A process for fabricating an electronic device comprising: (a) forming a liquid composition using starting ingredients comprising an n-type organic semiconductor selected from the group consisting of α,ω-di(perfluoroalkyl)substituted oligothiophenes, α,ω-diacyl substituted oligothiophenes, and metal perfluorophthalocyanines, and mixtures thereof and a stabilizer, wherein the stabilizer comprises a strong electron donor compound selected from the group consisting optionally substituted triarylamines, tetrathiafulvalene and its derivatives, optionally substituted polythiophenes, poly(3,4-ethylenedioxythiophene), 4,4′-bis(carbazol-9-yl)-biphenyl, poly(N-vinylcarbazole), polyaniline, and mixtures thereof, wherein the organic semiconductor exhibits a high oxygen sensitivity in a comparison solution without the stabilizer but a lower oxygen sensitivity in the liquid composition; (b) liquid depositing the liquid composition; and (c) drying the liquid composition to form a layer of the electronic device, wherein the layer comprises the organic semiconductor.
