Single molecule electrochemistry in nanoscale junctions

A number of techniques give the ability to tether single molecules between metallic electrodes and to measure their electrical properties. Such techniques can be deployed across a wide range of environments, but importantly for electrochemists they can be applied in electrolytes and with full electrochemical control of both contacting electrodes. This article discusses how such techniques have emerged as powerful tools for analyzing charge transport in single molecule junctions at electrode|electrolyte interfaces and gives outlooks for the future development of this field of single molecule electrochemistry in nanoscale junctions.
