A programmed light-responsive chiral liquid crystal is newly designed, precisely synthesized and efficiently applied as a remote-controllable molecular knob, by K.-U. Jeong and co-workers on page 4242. Photo-induced phase transformations in the mesomorphic helical superstructures enable the fabrication of optically tunable thin films which can be used as smart windows, multifunctional paints, and colorimetric sensors.
