Abstract

Liquid-crystal (LC) composites based on a combination of different acrylates and pentylcyanobiphenyl and containing CdSe/ZnS semiconductor quantum nanorods have been investigated. Samples of electro-optical cells with planar or homeotropic structures (depending on the acrylate type) have been obtained. The morphology of LC composite formation has been studied using luminescence techniques. It is shown that these composites are gel-like LC media, where the formation of dispersed and network structures in the cells plays a stabilizing role. The role of the electron transfer reactions during polymerization and the features of the kinetics of the Freedericksz effect (reorientation in an electric field) are discussed.
