The diaminoacid derivatives of protoporphyrin IX are promising in applications as photosensitizers in diagnosis and photodynamic therapy. Particularly derivatives with good water-solubility generate a lot of interests. It has been shown that due to the presence of selected amino acids residues attached to the porphyrin ring, these novel compounds penetrate more easily into tumor tissues and also clear from healthy tissues faster than others protoporphyrin-based photosensitizers. Nevertheless, the knowledge about chemistry and physical properties of these materials it still not sufficient. The one of not answered question is the role of Fe ions.
