Quinone Redox-active Ionic Liquids

Abstract

Simple ionic liquids exhibit unique physical and chemicalproperties that make them very useful for deployment in electrochemicaldevices such as solvent-free electrolytes in capacitors and batteries.However, incorporating redox functionality into ionic liquidstructures opens up in situ faradaic electrochemistry which allows accessto a large array of new electrochemical applications reliant uponheterogeneous or homogenous electron-transfer processes. This paperpresents and discusses the opportunities and challenges for these typesof electro-materials across a myriad of applications by consideringexemplar quinone-functionalised ionic liquids.
