Poly(azomethine)s containing thiophene with bridges pyridine, sulfur 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 IR spectroscopy (FT-IR), UV-visible spectroscopy (UV-Vis), hydrogen and carbon NMR spectroscopy. The some properties of poly(azomethine-thiophene)s were investigated such as optic, electronic, surface and thermal. Electrochem. and fluorescence properties of compounds were made by cyclic voltammetry (CV) and fluorescence anal., resp. 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 520 nm, resp., in this solution The fluorescence quantum yields of PAZ-Th-1 were found. According to thermogravimetric (TG) and differential scanning calorimetry (DSC) analyses, Tonset and glass transition temperature of PAZ-Th-1, PAZ-Th-2 and PAZ-Th-3 were found. Also, surface analyses of synthesized poly(azomethine-thiophene)s were photographed by scanning electron microscope (SEM) at room temperature The experimental part of the paper was very detailed, including the reaction process of 2,6-Diaminopyridine(cas: 141-86-6Electric Literature of C5H7N3)
