ORGANIC SEMICONDUCTOR PARTICULATE MATERIAL, ORGANIC SEMICONDUCTOR THIN-FILM, DISPERSION LIQUID FOR FORMING ORGANIC SEMICONDUCTOR FILM, METHOD FOR PRODUCING ORGANIC SEMICONDUCTOR THIN-FILM, AND ORGANIC THIN-FILM TRANSISTOR

摘要

Provided are a fine-particulate organic semiconductor material, a thin organic semiconductor film and an organic transistor. The fine-particulate organic semiconductor material is in a form of fine particles and is usable as an organic semiconductor material. The fine particles are fine thermotropic liquid crystal particles that undergo a phase transition into a liquid crystal state when heated to a temperature of from 50°C to 350°C. The fine-particulate organic semiconductor material can easily and uniformly form the thin organic semiconductor film over a large area by a film printing process or a dispersion coating process. The thin organic semiconductor film has high electron mobility and high ON/OFF value.
