LIQUID CRYSTALLINE ORGANIC SEMICONDUCTOR MATERIAL, AND SEMICONDUCTOR ELEMENT OR INFORMATION RECORDING MEDIUM USING THE SAME

摘要

The present invention provides a practical liquid crystal organic semiconductor material as an organic semiconductor. ; liquid crystalline organic semiconductor material of the present invention is a liquid crystal composition having a Smectic phase as a liquid crystal phase, to then not only has a distyryl benzene structure represented by the general formula (1), heated to a smectic temperature range of the liquid crystal state , characterized in that the state of the solid-state phase transition from occurring in the smectic phase by temperature reduction. ; Formula 1 ; (In the formula, R ¹ , R ² represents any one of groups represented by an alkyl group, an alkoxy group or the following general formula 2. Also, R ^{1 Yes} , R ² are the same or different groups may date) ; Formula 2 ; (In the formulas, R ³ is a hydrogen atom or a methyl group, B is - (CH ₂ ) _m -, - (CH ₂ ) _m -O-, -CO-O- (CH ₂ ) _m , -CO-O- (CH ₂ ) _m -O-, -C ₆ H ₄ -CH ₂ -O-, or represents a -CO-)
