ORGANIC SEMICONDUCTOR MATERIAL AND ORGANIC FIELD EFFECT TRANSISTOR

摘要

Disclosed is an adequately stable organic semiconductor material which can be used in a coating process while having high regularity and crystallinity. For obtaining such an organic semiconductor material, there is used a compound wherein 6-20 five-membered and/or six-membered aromatic rings are bound. This compound contains a partial structure represented by the formula (1) below, while having a mobility of not less than 1.0 × 10<SUP>-3</SUP> cm<SUP>2</SUP>/Vs and an ionization potential in the solid state of not less than 4.8 eV and not more than 5.6 eV. (1) In the formula, R<SUP>1</SUP> and R<SUP>2</SUP> independently represent a hydrogen atom or a monovalent organic group. In this connection, at least one of R<SUP>1</SUP> and R<SUP>2</SUP> is an optionally substituted aromatic group.
