ORGANIC SEMICONDUCTOR MATERIAL, ORGANIC SEMICONDUCTOR FILM, ORGANIC SEMICONDUCTOR DEVICE, AND ORGANIC THIN FILM TRANSISTOR

摘要

Disclosed is a molecular design of an organic semiconductor material which is useful for thin film transistors. Also disclosed are an organic semiconductor film, an organic semiconductor device and an organic thin film transistor respectively using the designed organic semiconductor material and exhibiting high carrier mobility, high ON/OFF ratio and high durability (improved oxidation stability and long-term stability). Specifically disclosed is an organic semiconductor material containing a compound having a partial structure composed of an aromatic fused polycyclic ring wherein three or more rings are fused. This organic semiconductor material is characterized in that the aromatic fused polycyclic ring has three or more substituents represented by the following general formula (1).
