Abstract :This study aimed to synthesize an oligoinsert ignore into journalissuearticles values(azomethine-ether); with benzothiazole moiety in organic medium by means of chemical oxidative polycondensation insert ignore into journalissuearticles values(OP);. Optical properties were examined by photoluminescence insert ignore into journalissuearticles values(PL); and UV-Vis measurements both in solutions and solid film involved a poly insert ignore into journalissuearticles values(methyl methacrylate); insert ignore into journalissuearticles values(PMMA); matrix. Oligomer film in the PMMA matrix emitted a fine green light with a fluorescence quantum yield insert ignore into journalissuearticles values(QY); of 3.30%. Spectral and thermal observations showed a high rate of C--O--C coupling insert ignore into journalissuearticles values(cross-linking); for the oligomer. SEC results indicated low molecular weight insert ignore into journalissuearticles values(\sim3200--4650 g mol^{-1}); and the oligomer was soluble in organic solvents with high polarity. Electrochemical behavior was characterized by cyclic voltammetry insert ignore into journalissuearticles values(CV);, morphological properties by scanning electron microscopy insert ignore into journalissuearticles values(SEM);, and thermal characteristics by TG-DTA and DSC techniques.
