【Abstract】 Novel high-ordered stack-of-card arrangement aggregations of 5-(4-hydroxyphenyl)-10,15,20-tri-(4- hexadecyloxyphenyl) porphyrin (P) in 20%-50% dioxane aqueous solutions were observed by means of UV-Visible spectra, fluorescence spectra ,TEM, DSC ect. The sizes of the aggregations were in the range of 65-150nm. The angle between the line-of centers and one transition dipole is less than 54.7° while that between the line-of centers and the other transition dipoles was greater than 54.7°, which correspond to the split of the Soret band of P. The aggregation changes to monomer with temperature increasing.更多还原
