摘要：Lquid crystals are states of condensed matter whose symmetries lie between crystals and isotropic liquids Thermotropic liquid crystalline phases are exhibited by a large number of organic compounds shows molecules have anisotropy of shape. A typical intermolecular energy responsible for the stability of the relevant order in the medium is intermolecular energy and thus liquid crystals are soft materials. Relatively weak interactions like those between molecular dipoles or chiral centers of appropriate molecules can give rise to new types of liquid crystals. The soft nature of the medium, coupled with anisotropic optical and properties gives rise to many electro-optic effects. This is first time we prepared grown crystal form the solution of mixtures by the S.R .Method. We studied the properties like viscosity, surface tension and crystal structure of a chloretryl chloride and chlorestryl nanoate mixtures which shows the effective changes. An analysis of the molecular arrangement in samples is performed by the spectroscopic techniques. Liquid crystals exhibit interesting viscoelastic properties. The study of viscoelastic modes in them is important not only on understanding the structural dynamics but also in selecting suitable materials for display devices. In liquid crystals, thermal fluctuations in the average direction of orientation of the molecules result in strong fluctuations in the dielectric tensor causing intense scattering of light.
