摘要：

(Figure Presented) Take the "H-bond" train: Introduction of a hydrogen-bond relay efficiently mediates the electron-transfer triggered exchange of protons between two sites over large distances (see picture). Thanks to this concerted proton-electron transfer mechanism, protonation of the relay group is avoided. © 2010 Wlley-VCH Verlag GmbH & Co. KCaA.
