Abstract: A possible way to speed up the operation of liquid crystal structures based on nematic mixtures with a charge transfer complex between a fullerene and an organic molecule donor fragment is studied using pyridine and polyaniline monomers and polymers as systems with the donor–acceptor interaction. Self-organization is established to occur in such structures. A more than an order of magnitude reduction in switching time is shown to be achievable. A possible physical mechanism of accelerating the liquid crystal dipole reorientation stimulated with intermolecular complex formation is discussed.
