Flexible construction of permanently stored supramolecular chirality with stimulus-responsiveness remains a big challenge. Herein, we describe an efficient method to realize the transfer and storage of chirality in intrinsically achiral films of a side-chain polymeric liquid crystal system by combining chiral doping and cross-linking strategy. Even the helical structure was destroyed by UV light irradiation, the memorized chiral information in the covalent network enabled complete self-recovery of the original chiral superstructure. These results allowed the building of a novel chiroptical switch without any additional chiral source in multiple types of liquid crystal polymers, which may be one of the competitive candidates for use in stimulus-responsive chiro-optical devices. 相似文献

This article is one of a number of reviews in a special issue to honor Prof. Dr. Ian Manners of the University of Bristol,
UK, for his outstanding contributions in the field of organometallic polymers. The focus of this review is on the syntheses,
properties, and characterization of ferrocene-containing liquid crystalline polymers in which ferrocene moieties are in or
pendent to the backbone and also dendrimers and [60]fullerene-ferrocene liquid crystalline materials. 相似文献
