CoFe 普鲁士蓝类似物 (PBA) 中与 Co 离子配位的水分子的酸度已被用来可逆地激活 (CoFeII)-Fe-III (CoFeIII)-Fe-II 电子转移。结构和电子结构的研究表明，该过程意味着固态多孔配位聚合物与溶液中氢氧根离子之间发生原始PCET反应。由于 PBA 孔隙通道内的长程 H+ 和 Rb+ 传输利用沸石水分子的氢键网络作为质子线，PCET 反应在整个固体网络中扩散。
Acidity of water molecules coordinated to Co ions in CoFe Prussian blue analogues (PBA) has been used to reversibly activate the (CoFeII)-Fe-III (CoFeIII)-Fe-II electron transfer. The study of the structure and the electronic structure shows that the process implies an original PCET reaction between a solid-state porous coordination polymer and hydroxide ions in solution. The PCET reaction spreads throughout the solid network thanks to a long-range H+ and Rb+ transport within the pore channels of PBA taking advantage of the hydrogen-bonding network of zeolitic water molecules acting as proton wires.
