Paper Abstract

Electric and optical properties of ionic lyotropic liquid crystals (ILLC) with different ionic polymethine dyes (cation- and anion-types) as well as neutral fluorescein (DILLC) are studied. Dielectric characteristics of the ILLC and DILLC are investigated before and after applied stationary electric field. The comparison analysis of the electric and electro-optical properties of different DILLC has been carried out. Stationary electric field, which exceeded a certain voltage (~6V), causes DILLC irreversible electrochemical changes and bleaching films. It has been established that the influence of electrodes, DILLC boundary layers and near electrode electrochemical processes give the main contributions to the electro-optical effects in DILLC.
