Poly(azomethine)s containing thiophene with bridges pyridine, sulphur and oxygen were synthesized in two steps. Before, thiophene centric dialdehyde (DIAL-Th) compound was synthesized via elimination reaction of 4-hydroxy benzaldehyde with thiophene bromide. Then, poly(azomethine)s containing thiophene (PAZ-Th) unit were synthesized from condensation reactions of DIAL-Th with pyridine-3,5-diamine, 4,4 '-thiodianiline and 4,4 '-oxydianiline. The obtained dialdehyde and poly(azomethine- thiophene)s were ratified by fourier-transform infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV-Vis), hydrogen and carbon nuclear magnetic resonance spectroscopy (H-1-C-13-NMR) measurements. The some properties of poly(azomethine-thiophene)s were investigated such as optic, electronic, surface and thermal. Electrochemical and fluorescence properties of compounds were made by cyclic voltammetry (CV) and fluorescence analysis, respectively. According to fluorescence measurement, PAZ-Th-1 was interestingly demonstrated five different colors in DMF solution. Blue, green, yellow, orange and red were observed at 420, 440, 480, 500 and 520nm, respectively, in this solution. The fluorescence quantum yields of PAZ-Th-1 were found to be 4.0, 15.0, 18.0, 6.4 and 6.2% at 420, 440, 480, 500 and 520nm, respectively. According to thermogravimetric (TG) and differential scanning calorimetry (DSC) analyses, T-onset and glass transition temperature of PAZ-Th-1, PAZ-Th-2 and PAZ-Th-3 were found as 256, 248, 224 degrees C and 162, 176, 137 degrees C, respectively. Also, surface analyses of synthesized poly(azomethine-thiophene)s were photographed by scanning electron microscope (SEM) at room temperature.
