Abstract

Charge-transfer (CT) dynamics has been investigated for Prussian blue-type M_A-Fe cyanides (M_A = Mn, Fe, and Co) 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 d⁶ state at the M_A site.
