Abstract
A new series of Schiff bases were synthesized by the condensation of sulfaproxylene with various aldehydes in ethanol. The structures of Schiff bases were characterized by using elemental analysis, IR, 1H NMR, 13C NMR and Mass spectrometry techniques. Thermal stability of the prepared compounds was investigated using TG and DTG. The kinetic and thermodynamic parameters such as activation energy (E), enthalpy of activation (ΔH), entropy of activation (ΔS), and Gibbs free energy change of the decomposition (ΔG) were evaluated following Coats-Redfern method. In addition, the compounds were studied for their fluorescence properties, where compound 1 yielded the strongest intensity in 1×10-4 M DMSO solution.
