Lyotropic mesomorphism and morphology in non-aqueous solutions of three tetranuclear platinum mesogens with different halogen-bridged groups

The lyotropic mesomorphism and morphological properties of a new type of lyotropic liquid crystalline system, i.e. a tetranuclear platinum mesogen/apolar organic solvent, have been investigated. The texture transformations in a large temperature interval, especially in the phase transition regions have been studied. The temperature widths of the heterophase regions of the nematic–nematic and nematic–isotropic liquid phase transitions have been determined with a high accuracy.
