The degradation of sensitizers used in photodynamic therapy (PDT) involves photooxidation either by molecular oxygen or by oxygen intermediates which leads to hydroxyaldehyde and formyl products or to ring opening. Our investigations focused on the spectroscopic changes which protoporphyrin-dimethylester (PP)
The fluorescent properties of the complexes of apoMb-PPIX and dimethyl-PPIX were studied in a wide range of pH and ionic strength. The quenching of fluorescence of PPIX in the complex by I- is shown to be of dynamic type Increasing

Complex formation of 5-coordinated iron(III) heme containing thiolate anion (p-nitrothiophenol) with imidazole (1-methylimidazole) showed very interesting features depending on the nature of the solvent and the ratio of the ligand to heme. The complexes formed under different conditions were not
The formation of triplet states of photosensitizers and singlet oxygen during reactions sensitized by protoporphyrin IX dimethyl ester (PPDME) and the products of its photo-oxidation in solution were studied by time-resolved spectroscopy. Irradiation with long-wavelength light (670 nm), which is
Normal coordinate analysis has been carried out for the Fe(III) protoporphyrin IX dimethyl ester molecule and its vinyl deuterated analogs. All atoms of substituents were included explicitly in the calculations. On the basis of the calculation results the assignment of
