A Theoretical Treatment of Charge-Transfer Interaction in an Aqueous Solution of Polyelectrolyte

Molecular orbital theory was adopted to explain theoretically the charge-transfer (CT) complexation of aromatic ions (donors) with 9,10-anthraquinone-2-sulfonate (acceptor) in an aqueous solution of polyelectrolyte. By the approximation of the theory, a distinct linear relation between the energies of the CT absorption band and ionization potentials of the donor molecules has been derived although the stoichiometric ratios of CT complexes which formed around the polyion were different.
