Influence of the microstructure of polymer gels on the electron-excitation energy transfer between organic molecules

The electron-excitation energy transfer (EEET) between ionic dyes in polyelectrolyte-network polymers with a different space distribution of charged segments has been investigated. It has been established that the structure of network polymers influences the efficiency of the EEET in them mainly due to the formation of a fractal distribution of interacting molecules. It is shown that the efficiency of the EEET can be controlled by changing the number and arrangement of charged segments of polyelectrolyte networks. ©2005 Springer Science+Business Media, Inc.
