Abstract
Colorful cholesteric liquid crystal polymer network (CLCN) patterns have been applied for decoration and anti-counterfeiting. Generally, the handedness of the reflected lights is the same. In this paper, a chiral dopant derived from cyanostilbene is synthesized. Due to the isomerization and [2 + 2] photocycloaddition under the irradiation of the 365-nm UV light, it exhibits a great change in the helical twisting power. The cholesteric liquid crystal mixture prepared using this chiral dopant can be applied for rapid optical recording. Colorful CLCN patterns are also prepared, which can reflect both left- and right-handed circularly polarized lights. Namely, different patterns are observed through left- and right-handed circular polarizers. Due to the luminescent property of the chiral dopant and its isomers, circularly polarized luminescence is emitted from the CLCN films.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
