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

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.

Silicon-containing polyphilic bent-core molecules: The importance of nanosegregation for the development of chirality and polar order in liquid crystalline phases formed by Achiral molecules

Polyphilic molecules composed of a bent aromatic core, oligo(siloxane) units, and alkyl segments were synthesized, and the self-organization of these molecules was investigated. Most materials organize into polar smectic liquid crystalline phases. The swi
Sign reversal of the dielectric anisotropy in the chiral nematic phase of a copolysiloxane

, p. 217 - 227 (2007/10/03)
A chiral copolysiloxane was synthesized that exhibited an N* phase in the 9-41°C temperature range. A linear electro-optical response with the applied electric field was detected in the N* phase due to the electroclinic effect. At high electric fields, the linearity of the response was strongly affected by dielectric coupling. It was found, however, that the influence of dielectric coupling on the electro-optical response became zero at a particular temperature (T= 37°C), which was attributed to a sign reversal of the dielectric anisotropy.
