発明の名称 (英語) LIQUID-CRYSTAL MATERIAL, LIQUID-CRYSTAL FILM, METHOD FOR PRODUCING SAME, SENSOR, AND OPTICAL ELEMENT NEW コモンズ 新技術説明会
発明の概要(英語) A liquid-crystal material containing a cellulose derivative having a molecular structure represented by general formula (1A). In general formula (1A), X11, X12, and X13 each independently represent a single bond, an alkylene group, -(R14-O)h-, or-C(=O)-R15-; R11, R12, and R13 each independently represent a hydrogen atom, a group having an unsaturated double bond, or a hydrophobic group; R14 and R15 each independently represent an alkylene group; h represents an integer of 1-10; and n11 represents an integer of 2-800. However, at least one of R11, R12, and R13 represents a group having an unsaturated double bond represented by general formula (3C) and/or a C5-20 linear or branched acyl group.
従来技術、競合技術の概要(英語) BACKGROUND ART
The liquid crystal material, as well as the display material of the liquid crystal display, using the optical characteristics in recent years, has been pursued to adapt to the photonic device. As the liquid crystal material, for example, cellulose derivatives are known.
A cellulose derivative as the liquid crystal property, the hydrogen atom of the hydroxyl group of cellulose, carbamate (urethane) having a substituent is introduced into the cellulose derivative is disclosed (for example, see Patent Document 1).
In addition, the solvent (A), the solvent in the liquid crystal can be formed (A) (B) and cellulose derivatives, a mixture of a tetraalkoxysilane (C) and (I) a step of obtaining a mixed solution, the cellulose derivative (B) the liquid crystal of fluoride, a condensation of a tetraalkoxysilane (C) a step of obtaining a composite material (II), acid (E) by the processing of, the liquid crystal in the composite material (III) having the step of removing oxides, silica based chiral structure has been disclosed a method of manufacturing (for example, see Patent Document 2).
