Exploring Collective Substituent Effects: Dependence of the Lifetime of Charged States of Au25(SCnH2n+1)18 Nanoclusters on the Length of the Thiolate Ligands

Antonello, S.; Dainese, T.; Maran, F. Electroanalysis 2016, 28, 2771-2776. Electrochemical methods have been often successfully employed to study substituent effects, a field pioneered by Petr Zuman. Here we used cyclic voltammetry to explore a new dimension of the effect of substituents on the lifetime of electrogenerated species. 18 thiolate ligands were collectively changed in molecular…

Reducing properties of 1,2-dipyridyl-1,2-disodioethanes: chemical validation of theoretical and electrochemical predictions

Azzena, U.; Carraro, M.; Pisano, L.; Mocci, F.; Antonello, S.; Maran, F. RSC Adv. 2016, 6, 46813-46821. The reducing properties of highly delocalized radical anions and dianions of 1,2-di(hetero)arylethenes were investigated by theoretical calculations at the PBE0/6-311+G(d,p)/IEFPCM level. The results correlated nicely with the reduction potentials determined by analysis of the voltammetric curves for the reduction…
