Abstract

Abstract The entanglement process between water-soluble 5, 10, 15, 20-tetrakis (4- sulfonatophenyl)-21H, 23H-porphine and the amphiphilic cyclodextrin (CD) heptakis (2-ω- amino-O-oligo (ethylene oxide)-6-hexylthio)-β-CD and the occurrence of various species at different porphyrin: CD ratios were studied by a combination of UV/Vis absorption, fluorescence anisotropy, time-resolved fluorescence, resonance light scattering, and ...
