Multielectron redox chemistry of lanthanide complexes

The article "Multielectron redox chemistry of lanthanide Schiff-base complexes" written by researchers in our lab makes the cover of Chemical Science June issue. This paper shows the benefit of using Schiff bases as ligands of lanthanide complexes for multielectronic transfer.

Redox transfer of several electrons is a keypoint for CO2 catalytic conversion, for instance. Lanthanide ions, in the +2 oxidation state, are highly reactive and are thus very attractive as catalysts, but they are extremely difficult to handle, precisely because of their reactivity. It is however possible to work wih the "standard" +3 oxidation state thanks to "redox-active" ligands. The compounds described in this paper are the first mono- et bi-nuclear Ln(III) complexes exhibiting such multielectronic redox properties (2 or 4 electrons). The synthesis route is well suited to every lanthanide, and the versatility of Schiff bases chemistry will enable the tuning of the redox potential, of the steric properties, etc., to fit different needs.
