ORGANIC SEMICONDUCTOR MATERIAL CHARACTERIZED BY THIENOTHIOPHENE SKELETON

摘要

PROBLEM TO BE SOLVED: To provide an organic semiconductor which has high solubility in an organic solvent and is stable. SOLUTION: The organic semiconductor material is characterized in a thienothiophene skeleton shown by a formula. In the formula, substituents R1to R12each contain at least one of a hydrogen atom and a halogen atom, an aryl group, a heterocyclic ring group, an alkyl group, a fluoroalkyl group, an alkenyl group, a fluoroalkenyl group, an alkynyl group, a fluoroalkynyl group, an alkoxyl group, a fluoroalkoxyl group, an amino group, an amide group, an imino group, a carboxyl group, a hydroxyl group, an ester group, a nitro group, a nitryl group, a sulfide group, a mercapto group, a sulfonyl group, and a silyl group. Here, R2and R8are identical substituents other than a hydrogen atom, and R3and R9are identical substituents other than a hydrogen atom. Further, R4and R10are identical substituents other than a hydrogen atom. COPYRIGHT: (C)2010,JPO&INPIT
