Chiral Biobased Ionic Liquids with Cations or Anions including Bile Acid Building Blocks as Chiral Selectors in Voltammetry

Chiral ionic liquids (CILs), or (ILs) with chiral additives, are very attractive media for enantioselective electroanalysis, on account of their high structural order at the electrochemical interphase. A family molecular salts CIL properties is now introduced, based steroid building block deoxycholic acid implemented either in anion cation. Testing them as additives a commercial achiral IL, they enable voltammetric discrimination enantiomers model probe disposable screen-printed electrodes terms peak potential differences, which most desirable transduction mode enantiorecognition event. The enantiomer sequence same all selectors, consistent sharing configuration. This proof-of-concept widens application fields bile derivatives while also enriching still few families so far explored applications electroanalysis.
