Abstract

Three polymers containing pyridine N-oxide imine pendant moieties were prepared and examined. Although the appropriate low molar mass model compound is liquid crystalline, the polymers are not mesogenic. Two of them form fibers and clear, transparent glasses. Side reactions involving the N-oxide group during polymerization are postulated as leading to the lack of mesomorphism in these materials although the π-chromophore remains essentially intact for the bulk of the material as judged by UV-Vis and other spectral data. They may have NLO application as poled polymeric glasses.
