Paper Abstract

In this work we investigated structural, optical and non-linear optical properties of lyotropic liquid crystal (LC) composition with the electrochromic admixture of viologen. X-ray investigations showed the presence of smectic A liquid crystal phase in samples. We calculated the main values, which characterize samples' structure, and made conclusions about the influence of the admixture at LC matrix Under the action of static electric field we observed colouring of the samples, which depends on the value of the voltage applied and influences the absorption spectra. We provided an analysis of the dependence of colour intensity of LC composition on the admixture concentration. Basing on our previous works we interpreted processes running inside the samples under the action of the electric field and leading to colour change. We registered holographic recording for the composition of LC-viologen and made suggestions about the mechanism of recording.
