A chiral catalyst represented by formula (II) is provided. In formula (II), Y independently includes hydrogen, fluorine, trifluoromethyl, isopropyl, tert-butyl, CHor OCH, wherein m=1-10 and n=1-10. A heterogeneous chiral catalyst is also provided. The heterogeneous chiral catalyst includes the chiral catalyst represented by formula (II), and a substrate connected to the chiral catalyst. 

Chiral catalyst and heterogeneous chiral catalyst comprising the same

An optical device is provided, which includes a first transparent substrate, a second transparent substrate, and a liquid-crystal material disposed between the first transparent substrate and the second transparent substrate. The liquid-crystal material includes a photo responsive material with a chemical structure of: wherein Ais Aand Aare independently X is halogen. R is H, Calkyl group, or Calkoxy group. R' is Calkyl group.

Photo responsive material and optical device

A zoom lens is provided, which includes an electrode pattern on a substrate, and a liquid-crystal material on the electrode pattern. The electrode pattern includes a plurality of concentric ring electrodes surrounding an innermost electrode. Each of the concentric ring electrodes has an opening. A first trace extends from a first electrode out of an outermost concentric ring electrode to the innermost electrode. The first trace has greater resistance than the concentric ring electrodes and the innermost electrode. A second trace connecting the innermost electrode and a second electrode out of the outermost concentric ring electrode through the openings. The liquid-crystal material includes a liquid-crystal compound with a chemical structure of wherein R is Calkyl group, n=1 or 2, and each of X is independently H or F.
