Polarizable potential window at soft molecular interfaces as a quantitative descriptor for the water content in organic solvents.

ABSTRACT: The presence of water in organic solvents is a ubiquitous fact and can affect the reactivity and selectivity of chemical reactions. Traditional physical and chemical methods (IR, NMR, Karl Fischer titration, etc.) for quantitative measurement of water in organic solvents are not very suitable for rapid trace water analysis. Here, we demonstrate that, with hydrated Li⁺ and Cl^- as probes to build polarizable potential windows (PPWs) at interfaces between water and more than twenty organic solvents, we can reflect the water content in organic solvents. This method only requires a scan of a cyclic voltammogram for Li⁺ and Cl^- transfer (a weak-interaction electrochemical method), at a micro-scale polarized water/oil interface. A hybrid modified
