ORGANIC SEMICONDUCTOR MATERIAL AND ORGANIC FIELD EFFECT TRANSISTOR

摘要

To provide an organic semiconductor material which can be subject to a coating process, and has high regularity, high crystallinity, and high stability, a compound having 6 to 20 five-membered and/or six-membered aromatic rings bonded to each other, and having a partial structure represented by the formula (1) below; having a mobility of 1.0×10 -3 cm 2 /Vs or more, and having an ionization potential in the solid state in the range of 4.8 eV to 5.6 eV is used. In the formula, R 1 and R 2 independently represent a hydrogen atom or a monovalent organic group, provided that at least one of R 1 and R 2 is an optionally substituted aromatic group.
