Charge transfer complexes of aryl 2-azomethine dibenzothiophene with π-acceptors viz., 1,3-dinitrobenzene, 2,4-dinitrophenol and picric acid were synthesized and characterized by spectroscopic techniques viz., IR, 1H NMR and elemental analysis. The equilibrium constant (k) was determined using modified Benesi-Hildelbrand methods. The stoichiometries of the reactions were determined using photometric titration methods. The thermodynamic parameters Gibbs free energy (ΔG), enthalpy (ΔH) and entropy change (ΔS) were also calculated. Theoretical calculations have been carried out by density functional theory (DFT) and time-dependent density functional theory calculations.
