ORGANIC SEMICONDUCTOR MATERIAL AND ORGANIC THIN FILM TRANSISTOR EMPLOYING IT, FIELD EFFECT ORGANIC THIN FILM TRANSISTOR AND SWITCHING ELEMENT EMPLOYING THEM

摘要

PROBLEM TO BE SOLVED: To provide an organic semiconductor material having high carrier mobility in which aging is improved, and to provide a field effect organic thin film transistor having large current on/off-ratio characteristics in which aging is improved.;SOLUTION: The organic semiconductor material comprises a compound having a heterocycle unit represented by a chemical formula (1) {where, A¹ represents -O-, -S- or -N(R₁)- (R₁ represents a hydrogen atom or a substituent), A² represents -N= or -C(R₂)= (R₂ represents a hydrogen atom or a substituent), and A³ represents -N= or -C(R₃)= (R₃ represents a hydrogen atom or a substituent)} in a molecular structure.;COPYRIGHT: (C)2005,JPO&NCIPI
