Different aggregation behaviors of amphiphilic porphyrins in the aqueous and salt aqueous solution

The UV-Vis spectra of amphophilic porphyrins in aqueous and salt solution were analyzed at neutral condition. The results show that the substituted hydroxylphenyl and hexadecyl chains of ampiphilic porphyrins and the addition of salt affect the aggregation behaviors of porphyrins. The aggregating ability of amphiphilic porphyrins were explained primarily.
