LIQUID CRYSTAL MATERIAL, LIQUID CRYSTAL FILM AND PRODUCTION METHOD OF THE SAME, SENSOR, AND OPTICAL ELEMENT

Japanese Patent JP2018048289

A

PROBLEM TO BE SOLVED: To provide a liquid crystal material, from which such a liquid crystal film can be produced, showing thermotropic cholesteric liquid crystallinity, has elasticity and has an alignment immobilized at a wavelength of Bragg reflection.SOLUTION: The liquid crystal material contains a cellulose derivative having a molecular structure represented by formula (1A) or formula (1B). In the formulae, X, X, X, Xand Xeach independently represent a single bond, an alkylene group or the like; R, R, R, Rand Reach independently represent H, a group having an unsaturated double bond, or a hydrophobic group; n11 represents an integer of 2 or more and 800 or less; n12 represents an integer of 2 or more and 800 or less; and Lrepresents an alkyl group.SELECTED DRAWING: None
