Özet

In this study, poly(azomethine)s with cresol and pyrrole as side chain units were synthesized in three steps. In the first step; symmetrical dialdehyde bromide (DAB), in the second step; symmetrical derivatives (DAB-1 and DAB-2) of DAB using p-cresol and pyrrole, respectively, and in the third step; poly(azomethinecresol) (P-1) and poly(azomethine-pyrrole) (P-2) were obtained via condensation reaction. Structures of all synthesized compounds were confirmed by FT-IR, UV-Vis, and H-1 NMR spectroscopic analyses. Photophysical and electrochemical properties of these compounds were investigated using photoluminescence (PL) and cyclic voltammetry (CV) measurements, respectively. Based on photoluminescence analysis, the multicolor properties of DAB-2, P-1 and P-2 were observed in DMF solution. Additionally, results of thermal studies of TG-DTA and DSC techniques showed they were thermally stable compounds.
