dc.description.abstractIn this study, a family of azomethine-based thiocarbohydrazone monomers and polymers prepared and their structurally characterized by FT-IR, 1H-13C NMR and UV-Vis techniques. The electrochemical behaviors, fluorescent activities, thermal characteristics, antioxidant effectiveness of synthesized compounds were determined by cyclic voltammetry (CV), fluorescence (FL) spectroscopy, thermogravimetric-differential thermal analysis (TG-DTA), differential scanning calorimeter (DSC) and CUPRAC techniques, respectively. Fluorescence quantum yields of Poly-SATCH, Poly-BSATCH, Poly-MSATCH, Poly-NATCH were calculated to be 4.1, 9.4, 11.4 and 7.4 % in 0.025 mg mL-1 concentrations in DMF solutions in the range of 3 nm slit at 440, 420, 400 and 340 nm, respectively. The antioxidant values of monomer and polymers were changed between 0.30 +/- 0.029 and 3.54 +/- 0.719 against CUPRAC technique. The glass transition temperatures of Poly-SATCH, Poly-BSATCH, PolyMSATCH and Poly-NATCH were found to be 116, 134, 138 and 139, respectively.
