Abstract: Both the aligning effect of erythrocytes in nematic liquid crystal media and the phenomenon of induced rearrangement of pristine nematic liquid crystal have been observed. Reasons for structuralization of the nematic liquid crystal under the action of inserted nonelectrically- neutral biological components have been discussed. The observed effect is suggested to be quite general and consistent with previously obtained results for nematic liquid crystal under the action of fullerene-containing charge transfer complexes.

Abstract: The fullerene-doping effect on spectral, nonlinear optical properties, and dynamic parameters of conjugated organic systems based on pyridine, polyimide, polyaniline, polyvinyl alcohol, liquid crystal, etc. has been studied. Introduction of fullerenes into these materials has been made due to their high electron affinity that allows intermolecular donor-acceptor interaction to be reinforced. The new charge transfer complex provokes new nanostructures potentials such as nonlinear transmission, laser-induced change in the refractive index, self-organization. The application of studied nanostructures in laser and display techniques, and medicine has been discussed.

Abstract: Fullerene-doped liquid crystal compounds have been considered as new nanostructured materials with promising photosensitivity and speed parameters. Self-organization in liquid crystal mesophase based on charge-transfer complexes between an organic donor and fullerene has been investigated. The switch-on time of 50 μs has been obtained. The results are discussed from the viewpoint of increasing the system polarizability and a possible transition from the nematic phase to the smectic one, which is caused by a complex formation.
