| Abstract: | ′ ,4′′,4′′′-tetrasulfonato-phthalocyanine/N-butyl-N′-methylanthraquinone-4,4′-bipyridinum dibromide assembly (ZnTsPc-V-AQ), was observed to be enhanced by ten times when the sample was optically pumped
by a 355 nm pump beam. The enhancement of the nonlinearity was found to be due predominantly to the charge transfer between
the two monomers of the supramolecule after optical excitation.
