Branched redox-active complexes for the study of novel charge transport processes

Abstract

The syntheses and electrochemical/optical properties of some branched and linear 1,1′-substituted ferrocene complexes for molecular electronics are described. Metal centers were extended (and where relevant, connected) by arylethynyl spacers functionalized with m-pyridyl, tert-butylthiol (S tBu), and trimethylsilyl (TMS) moieties. Such systems provide two well-defined molecular pathways for electron transfer and hold interesting prospects for the study of new charge transport processes, such as quantum interference, local gating, and correlated hopping events. © 2013 American Chemical Society.
