Abstract
Photosensitized electron transport from ethylenediaminetetraacetic acid disodium salt (EDTA·2Na) or sodium ascorbate (Asc·Na) to methylviologen (MV++) across vesicle membranes of dipalmitoyl-l-α-phosphatidylcholine (DPPC) which incorporate 5,10,15-tris(1-methylpyridinium-4-yl)-20-[4-(octadecyloxy)phenyl]porphinatozinc(II) trichloride (Zn–P) asymmetrically (only on the outer side of the membrane) is facilitated by an electron mediator such as ubiquinone Q10 (UQ10) or tetraphenylporphine (TPP). Zn–P plays an important role in the redox reaction at the interface of the vesicles and the efficiency can be correlated with the redox potentials of the mediators.
