N2 - Ten ionic liquids (ILs) based on glycine cations with bis(trifluoromethanesulfonyl)amide or alkylsulfate anions as novel electrolytes are prepared and evaluated. The ILs exhibit wide electrochemical windows of 5.0 V and good ionic conductivity (up to 1.44 mS cm-1 at 35 °C). The Stokes-Einstein products of two organometallic redox couples, Fc/Fc+ (ferrocene/ferrocenium) and Cc/Cc+ (cobaltocene/cobaltocenium), and an organic redox couple TMPD (N,N,N′,N′-tetramethyl-para- phenylenediamine) in the ILs are determined. The solvodynamic radii of Fc, Cc, and TMPD are found to be independent of the types of ILs.
