Water‐Switching of Spin Transitions Induced by Metal‐to‐Metal Charge Transfer in a Microporous Framework

Water‐switchable charge transfer: The microporous hydrated phase {[Fe(Tp)(CN)3]2Co(bpe)}⋅5 H2O shows spin transition induced by metal‐to‐metal charge transfer (MMCT), but no MMCT is observed in the corresponding dehydrated phase (see picture). Charge transfer can be reversibly switched through de‐ a...

Summary:Water‐switchable charge transfer: The microporous hydrated phase {[Fe(Tp)(CN)3]2Co(bpe)}⋅5 H2O shows spin transition induced by metal‐to‐metal charge transfer (MMCT), but no MMCT is observed in the corresponding dehydrated phase (see picture). Charge transfer can be reversibly switched through de‐ and rehydration. Tp=hydrotris(pyrazolyl)borate, bpe=1,2‐bis(4‐pyridyl)ethane. Fe green, Co orange, N blue, O red, C gray, B dark yellow.
