Abstract

Dependence of displaying of lyotropic nematic polymorphism in binary systems tetranuclear palladium organyl/linear alkane from the ratio of number of carbon atoms of aliphatic mesogene substituents and alkane molecule was shown by the method of polmicroscopic analysis of contact preparates. For the first time it has been shown that two phases in nematic region could be resolved not only by polmicroscopic investigation, but also by far infrared Fourier transform (FTIR) spectroscopy.
