Abstract
One purpose of the present invention is to provide a liquid-crystal compound which exhibits liquid crystallinity at low temperatures. Another purpose of the present invention is to provide a thermally responsive material which exhibits liquid crystallinity and rubber elasticity at low temperatures (around room temperature) ever, though a large amount of a liquid-crystal compound is contained therein, and a method for producing this thermally responsive material. A liquid-crystal compound according to the present invention is obtained by adding an alkylene oxide and/or styrene oxide to a mesogenic group-containing compound that has an active hydrogen group.
