Abstract
3,8‐Diformyldeuteroporphyrin dimethyl ester (1a) was obtained by ozonization of the diprotonated dication of protoporphyrin dimethyl ester 1b. Several derivatives have been prepared, which are either hydrophobic, or bear hydrophilic substituents in the „northern hemisphere”︁ of the porphyrin ligand or on both sides. The porphyrins have then been dissolved in aqueous media containing vesicles with electroneutral, ‐negative, or ‐positive surface charges. The localization of the dissolved porphyrin chromophore was determined spectroscopically following reactions of the central porphyrin nitrogen atoms or of peripheral substituents with water‐soluble acids or metal ions.
