Thermotropic mesogens, magnetic properties

Finally, it is necessary to indicate the broad possibilities of obtaining new materials for the creation of passive elements in optical devices and media for recording and storing information. Materialsl whose use is based on unusual optical, electrical, and magnetic properties of LC polymers cannot be developed if the properties themselves are not known. In evaluating the prospects of this direction of research, it is possible to build on the advances made in the study of thermotropic LC polymers with mesogenic groups in the side chain [82]. 

This review deals with LC polymers containing mesogenic groups in the side chains of macromolecules. Having no pretence to cover the abundant literature related to thermotropic LC polymers, it seemed reasonable to deal with the most important topics associated with synthesis of nematic, smectic and cholesteric liquid crystals, the peculiarities of their structure and properties, and to discuss structural-optical transformations induced in these systems by electric and magnetic fields. Some aspects of this topic are also discussed in the reviews by Rehage and Finkelmann 27), and Hardy 28). Here we shall pay relatively more attention to the results of Soviet researchers working in the field.
