Composition for manufacturing organic semiconductor device

Abstract

Provided is a composition for manufacturing an organic semiconductor device, the composition enabling formation of an organic semiconductor device that stably shows high carrier mobility. A composition for manufacturing an organic semiconductor device contains 2,3-dihydrobenzofuran as a solvent and an organic semiconductor material below, in which the water content of the solvent is 0.25 wt % or less. The organic semiconductor material: at least one compound selected from the group consisting of a compound represented by formula (1-1), a compound represented by formula (1-2), a compound represented by formula (1-3), a compound represented by formula (1-4), a compound represented by formula (1-5), and a compound represented by formula (1-6). wherein Xand Xare the same or different and each represent an oxygen atom, a sulfur atom, or a selenium atom, m is 0 or 1, nand nare the same or different and each represent 0 or 1, and Rand Rare the same or different and each represent a fluorine atom, a Calkyl group, a Caryl group, a pyridyl group, a furyl group, a thienyl group, or a thiazolyl group, in which 1 or 2 or more hydrogen atoms contained in the alkyl group may be substituted by a fluorine atom, and in which 1 or 2 or more hydrogen atoms contained in the aryl group, the pyridyl group, the furyl group, the thienyl group, and the thiazolyl group may be substituted by a fluorine atom or an alkyl group having 1 to 10 carbon atoms.
