Two new chiral liquid crystals containing a well-known mesogenic cholesteryl group and an azobenzene moiety connected with a short flexible carbonyldioxy spacer and a polar carbonyl unit in a terminal chain were designed and synthesized. A sequence of very interesting mesophases were observed. Their reversible photoresponsive properties were well-demonstrated by UV irradiation. The two materials as chiral mesogenic dye dopants have a very large solubility in a common nematic liquid crystal host, which can facilitate a large amount of doping to induce mesophase chirality and magnify the photocontrolling effect.
