In situ spectroelectrochemical studies focussing on the Franck-Condon region and sub-ns electron transfer processes in Ru(II)-tpphz-Pt(II) based photocatalysts reveal that single-electron reduction effectively hinders intramolecular electron transfer between the photoexcited...

Metal-to-ligand charge-transfer (MLCT) excited state lifetimes of [Fe(CN)4(2,2’-bipyridine)]2- and [Fe(CN)4(2,3-bis(2-pyridyl)pyrazine)]2-exhibit strong solvent and ligand dependence. We conclude that these effects can be described with Marcus-like model where changes in the MLCT energy correspond directly to the changes in the electron transfer driving force and all the other factors (e.g. reorganization energy) can be considered constant.
