Pre and Post electronic changes in charge transfer complex: Mini Review

Nampally Venkatesh, Tigulla Parthasarathy*

The UV electronic absorption spectra of several organic CT (Charge Transfer) interactions have showed appearance and/or disappearance of spectral CT-bands. The stoichiometry was determined by Job’s, spectrophotometric and conductometric titration methods. The conductivity values of the CT-complex are found to have the range of semiconductors indicating the dissociation of CTC to produce ionic species. The electronic change of CTC leads to the formation of protonated inner sigma complex. All spectral results confirm the formation of a thermodynamically stable mono substituted product via inner sigma complex. The DFT studies support the CTC and inner sigma complex.
