Abstract
In this study, the synthesis of three novel π-conjugated Schiff base monomers containing syringaldehyde unit were performed through condensation polymerization technique which is confirmed by NMR and IR spectroscopic techniques. Other characterization i.e. optical properties (fluorescence and UV–Vis), thermal (TG–DTA), electrochemical, Morphological characteristics are performed for the study of application potential of synthesized polymeric materials in organic electronics and voltaic. The resulting polymers were thermally stable up to 270 °C which is confirmed by TGA analysis. The electrochemical data shows the polymers exhibit low band gaps. Electrical conductivity study indicates that conductivity of polymers is in the range of ~ 10−5 S/cm at ordinary temperature. Dielectric study confirms that the capacity of polymers were 0.1–2.8 µF, permittivity of ~ 106 F/m and D factor of > 11.
