THE STUDY OF SPECTRAL PROPERTIES OF DIMETHYLESTER OF CHLORIN E6 IN THE PRESENCE OF POLYVINYLPYRROLIDONE
It was analysed different samples on the basis of dimethylester of chlorin e6 and different samples of polyvinylpirrolidone by the method of UV-Vis spectrophotometry. The influence of ratio photosensitizer-polyvinylpirrolidone was studied in different buffer solutions on spectral properties of dimethylester of chlorin e6. The obtained spectrums were also compared with those for chlorin e6 in the presence of polyvinylpirrolidone. It was proved, that molar mass of high-molecular component has a weak influence on spectral properties of investigated substance. The received results demonstrate the decrease of effect of di- and oligomerization of photosensitizer moleculs in the presence of highmolecular component, and the formation of complex of this substance with macromolecules of polyvinylpirrolidone. Carried out investigations give a foundation for perspective of further investigations for the production of dosage forms on the basis of dimethylester of chlorin e6 and polyvinylpirrolidone.
