Abstract: The deprotonation of an amphiphilic porphyrin, meso-tetra (p-hydroxylphenyl)porphyrin with a hexadecyl chain(THPPH2), has been observed by means of UV-Visspectroscopy in CTABmicellar solutions. With increasing of PHvalues, the Soret band shiftsfrom 424 nm to 441nm, and the four-Qbands (520 nm, 560 nm, 595nm, 655 nm) aredisappeared while two new Q-bands are appeared at 585 nm and 675 nm, which is similar tometal-porphyrin, means that the deprotonation of porphyrin takes place. Comparing withthe spectra in an other solutions, the spectral characteration of THPPH2 in neutral and inbasic CTABsolutions is similar to that in CHCl3 and basic aqueous solutions respectively,suggesting that the solubilizing location of THPPH2 takes a change from inner to the outer of theCTABmicellars with the PHvalue of solutions increasing between 6.20 and 11.19.

Key words: Amphiphilic porphyrin, Deprotonation, Solubilizing location, CTAB micella
