Abstract

In this study, synthesis, characterization and photophysical properties of the quinoline and azomethine derived polymers were described with ether linkages. Synthesis procedure was conducted in three steps; the first step, dialdehyde monomer, the second step poly(azomethine) (PA), and the third step poly(azomethine-quinoline) (PAQ) polymers were obtained with elimination and condensation reactions. The structures of synthesized compounds were confirmed with FT-IR, UV-Vis and H-1-C-13-NMR spectra. Electrochemical and photophysical behaviors were interpreted with cyclic voltammetry and photoluminescence data. In addition, thermal properties of compounds were obtained by TG and DSC techniques. Surface images of polymers were photographed with scanning electron microscope (SEM). Electrochemical band gaps (E'(g1)) of PA and PAQ were calculated as 2.19, 1.83 eV, respectively. The starting degradation temperatures of PA and PAQ were found as 126 and 184 A degrees C, respectively.
