Abstract

Paramagnetic moieties in mesogenic polymers can provide valuable information about macromolecular orientation. The results of EPR and polarized light investigations on three polyazomethines bearing hydroxyl groups and containing paramagnetic centers are reported. The micrograph in the Figure shows the threaded texture of a polyazomethine, derived from naphthalenediamine, containing oxovanadium(IV) centers.
