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.eninfo:eu-repo/semantics/closedAccessPoly(thiocarbohydrazone)Structure characterizationFluorescent activityFluorescence quantum yieldMultichromic emissionPhoto stabilityAntioxidantArticle28210.1016/j.mseb.2022.115782Q2WOS:0008084789000012-s2.0-85130797353Q1
