Özet:

 

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