Title:

ORGANIC SEMICONDUCTOR COMPOSITION, ORGANIC THIN FILM AND ORGANIC THIN FILM TRANSISTOR

Document Type and Number:

WIPO Patent Application WO/2018/174014

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide an organic semiconductor composition suitable for preparing an organic thin film by a solution method, an organic thin film obtained using the organic semiconductor composition, and a practical field effect transistor which uses the organic thin film, has small variations in mobility while maintaining a high mobility, and also has small variations in a threshold value. That is, disclosed in the present specification is an organic semiconductor composition including an organic semiconductor compound, an insulating compound, an organic solvent A which is a good solvent for the insulating compound, and an organic solvent B which is a poor solvent for the insulating compound and has a higher boiling point than the organic solvent A. The mass ratio a : b of the organic solvent A and the organic solvent B is 1 : 8 to 8 : 1.
