ABSTRACT
Measurements of the polarized absorption and fluorescence intensity for a liquid crystalline side chain polymer doped with a fluorescent dye have been used to study molecular orientational order in the polymeric matrix both in the glassy and mesomorphic phases. The intermolecular angle between the absorption and emission oscillators has been evaluated. It has been found that fluorescence spectroscopy is a sensitive method for determination of the glass-nematic transition temperature of liquid crystalline polymers.
