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 (similar to 3200-4650 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.
