Change in conformation of J-aggregate 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin (H2TPPS) by addition of nonionic surfactant (Triton X-100)

Drastic conformational change of J-aggregate of 5,10,15, 20-tetralcis(4-sulfonatophenyl)porphyrin (H2TPPS) was observed by addition of nonionic surfactant (Triton X-100) in acidic medium. The CD spectra of the aggregate (H4TPPS)(n) changed to opposite signed CD spectra in the presence of Triton X-100. The interaction of (H2TPPS)(n) with Triton X-100 was studied by the measurements of UV-vis and fluorescence spectra as well as CD spectra at different concentrations of Triton X-100.
