Prevention of photo-oxidation of metal-free phthalocyanine by incorporation into dioctadecyldimethylammonium bromide (DODAB) vesicles
Abstract
The normal photo-oxidation of tetra-1-butyl metal-free phthalocyanine was prevented by its solubilization in dioctadecyldimethylammonium bromide vesicles but was evident in dihexadecylphosphate vesicles where, using the spin-trapping technique, it was revealed that ·OH radicals were generated.
