By spectrophotometry and dynamic light scattering methods, the self-assembling processes in mixed aqueous solutions of second-generation photosensitizer Photosens (hydroxyaluminum trisulfophthalocyanine) and chitosan were investigated. It was established, that in dilute aqueous mixtures the Photosens and chitosan form supramolecular complexes with reproducible stoichiometric composition in these conditions, what corresponds the molar ratio of chitosan:Photosens = 2.3:1. It was found, that phthalocyanine in the composition of these supramolecular complexes presents in the form of H- and J-aggregates. Ability of chitosan to bind Photosens reduces with decrease of molecular weight of chitosan. The influence of pH and the presence of disaggregating additives on the complexation process of Photosens with chitosan was considered.
