Cholesteric fluorescent liquid crystal polysiloxanes with different liquid crystal side chain lengths—Synthesis and properties

Cong, Yue-hua,Gao, Shang,He, Xiao-zhi,Jia, Ying-gang,Liu, Ze-ping,Meng, Fan-bao,Zhang, Bao-yan

, (2020/07/03)

With polymethylhydrogensiloxane (PMHS) as the main chain, two series side-chain cholesteric liquid crystal polymers (ChLCPs) with different liquid crystal side chain lengths were prepared by hydrosilylation reaction. Then two series of cholesteric fluorescent liquid crystal polymers (FL-ChLCPs) were obtained by etherification reaction. The obtained FL-ChLCPs have both excellent mesomorphic behavior, and great photoluminescent property. We confirmed their chemical structures by FT-IR, and 1H NMR spectroscopy, and found them with excellent thermal stability by TGA. We characterized their mesomorphic behavior and thermal performance by POM, DSC and XRD, and confirmed all the polymers belonged to cholesteric phase. FL-ChLCPs emitted different-intensity fluorescence under UV light, and we found some regularity by PL spectrum.

Influence of interim alkyl chain length on phase transitions and wide-band reflective behaviors of side-chain liquid crystalline elastomers with binaphthalene crosslinkings

Wu, Xiaojuan,Cao, Hui,Guo, Renwei,Li, Kexuan,Wang, Feifei,Gao, Yanzi,Yao, Wenhuan,Zhang, Lanying,Chen, Xiaofang,Yang, Huai

experimental part, p. 5556 - 5566 (2012/08/28)

A series of side-chain polysiloxane liquid crystalline elastomers, E-Cm (where m is the number of carbon atoms in the interim alkyl groups, and m = 4, 6, 8, 10), with binaphthalene derivatives as crosslinkings, were designed and synthesized. The mesophase

V-Shaped switching and interlayer interactions in ferroelectric liquid crystals

Petrenko, Alexey,Goodby, John W.

, p. 766 - 782 (2008/02/01)

Linear electrooptic responses in ferroelectric liquid crystals can be achieved via thresholdless switching. The molecular parameters for the design of ferroelectric liquid crystals that may yield a thresholdless response have not been delineated so far. In this article we explore some of the chemical design features that may be utilised in controlling switching processes, and we develop property-structure correlations in order to achieve materials that exhibit thresholdless behaviour.
