N2 - Dynamics of the charge-transfer (CT) pairs has been investigated for the cyano-bridged Co2+ - Fe3+ particles grown in a hydrophilic cavities of Nafion 117 film. We decomposed the differential absorption spectra into the fast and slow components. We ascribed the fast and slow components to the Frank-Condon state and the CT (Co3+ - Fe2+) pairs with lattice relaxation, respectively. We found that the lifetime τCT of the pairs at 10 K increases with the absorbed photon density n from τCT ≈2 ns to ≈6 ns, reflecting the attractive interaction between the pairs.
