摘要：

Charge-transfer (CT) dynamics has been investigated for Prussian blue-type M-A-Fe cyanides (M-A = Mn, Fe, and Cc) grown in hydrophilic cavities of a Nafion 117 film. In all the compounds, we observed the suppression of the original CT absorption between neighboring transition metals. We found that the spectral profile of the slow component for the Fe compound is similar to that for the Co compound, reflecting the photo created d(6) state at the M-A site.
