Abstract

Optically active (see paper for formula) have been synthesized on the base of l-menthon and d-camphor. A possibility to use (alpha) - (beta) -unsaturated ketones in LCD as alloying dopants that are able to induce the helical regulation in the nematic phase is represented. The twisting power and temperature dependence of the induced pitch in the chiral nematic phase of LC compositions cyanobiphenyl and phenylcyclohexane have been investigated. The pitch of the helical chiral dopants basing on d-camphor is reduced when the temperature is increased. Thus they can be used for the reduction of temperature dependence of helical pitch in left-handed twisted dopants on the base of l-menthon.
