Paper Abstract

Recently the investigation of photoprocesses in organized synthetical structures (ionic micelles, vesicles, linear polyelectrolytes, polymer gels etc.), intermolecular interactions of which are formed by hydrophobic and electric forces, have been of great interest.12 These systems are of particular interest due to the possibility of using luminescent data, which reflected the peculiarities of photoprocesses in organized assemblies. This can be used to establishing the mechanism of photobiological processes. Due to the very complex nature of biostructures our approximation can be considered phenomenological, however it gives the possibility of revealing the energy dissipation path in biosystems. Such model approach is based on a principal resemblance between a living matter and synthetical polymolecular structures with a certain degree of organization. This resemblance is displayed in theoretical models of synthetic polymers,3 which are the foundation of modern ideas on biomolecule conformation. Organized synthetical structures like ionic micelles, polymer gel, bilayer and strong polyelectrolytes could be made to represent biosystems like cell, protoplasm, membrane and NADH, respectively. In this paper we report some new results on the complex formation of dyes and detergents in premicellar region and singlet-singlet energy transfer from pyrene (Py) excimer to dye monomers in ionic micellar-polyion-water system.
