| Abstract: | The spectrophotometric properties of thianthrene with iodine and tetracyanoethylene at 24°C in different solvents such as cyclohexane, carbon tetrachloride, chloroform, methylene chloride and 1,2-dichloroethane are found to depend on the solvent. In addition, the charge transfer complexes of thianthrene with p-chloranil and 2,3-dichloro-5,6-dicyano-p-benzoquinone at 24°C in methylene chloride solvent were studied, also spectrophotometrically. The spectral data, the equilibrium parameters and the dissociation energy of the excited charge transfer complexes were determined. The role of the electron donor and the electron acceptor structure on the formation and stability of the charge transfer complexes was discussed. |
