Abstract

The spectrophotometric properties of the charge-transfer (CT) complexes of benzo[<i>b</i>]thiophene with iodine at 24 °C in different solvents such as cychlohexane, carbon tetrachloride, chloroform, dichloromethane, and 1,2-dichloroethane are studied. In addition the spectrophotometric and thermodynamic properties of the CT complexes of benzo[<i>b</i>]thiophene with tetracyanoethylene, chloranil, 2,3-dichloro-5,6-dicyano-<i>p</i>-benzoquinone and 7,7,8,8,-tetracyanoquinodimethane are studied. The results show that the equilibrium and the thermodynamic parameters and the wavelengths of the maximum absorption bands (<i>λ</i><sub>max</sub>) of the complexes vary markedly with the solvent. The ionization potential and the donor sites of benzo[<i>b</i>]thiophene are also determined and discussed.
