This invention provides chiral thioindigo compounds for doping smectic liquid crystal hosts, wherein the compounds modulate a chiral bulk property of an induced chiral smectic liquid crystal phase upon irradiation at a wavelength in the visible range. Modulation of the chiral bulk property is effected...http://www.google.fr/patents/US5989451?utm_source=gb-gplus-shareBrevet US5989451 - Compounds and methods for doping liquid crystal hosts
