摘要: The study of nanosecond dynamics of macromolecules with the lumines-cent methods make it possible to investigate the formation and functioning of polymericcomplexes, polymeric conjugates and macromolecular metal complexes, which are widelyused for solving many practical tasks. The nanosecond dynamics of macromolecules are ahighly sensitive indicator of interpolymer complexes (IPC) formation. It enables us to solvethe problems of studying IPC formation and stability and to investigate the interpolymer reactions of exchange and substitution.The investigation of changes in the rotational mobility of globular protein molecules as a whole makes it possible to determine the complex composition and its stability,and to control the course of polymer-protein conjugate formation reaction.The nanosecond dynamics of polymers interacting with surfacants'ions(S) are the sensitive indicator of the S-polymer complex formation.A method for determining the equilibrium constants of the S-polymer complex formation was developed on the basis of the study of polymer chains mobility.It is established that nanosecond dynamics influences the course of chemical reactions in polymer chains.Moreover,the marked effect of the nanosecond dynamics is also revealed in the study of photophysical processes (the formation of excimers and energy migration of electron excitation)in polymers with photoactive groups.It was found that the efficiency of both processes increases with increasing the mobility of side chains,the carriers of photoactive groups.
