Synergistic effects of β‐CD and chiral ionic liquids in a dual selector system, illustrated with the enantioseparation of chiral drugs econazole (A) and sulconazole (B). The use of a single chiral selector, (2‐hydroxypropyl)‐β‐CD shown in the bottom trace, was compared to two dual selector systems including (2‐hydroxypropyl)‐β‐CD and either the chiral ionic liquid [TBA][L‐Glu] shown in the top trace, or [TBA][L‐Lys] shown in the middle trace. Enhanced resolution was observed for both chiral drugs when using a dual selector system, compared to only employing (2‐hydroxypropyl)‐β‐CD. Rs = resolution. Adapted from [170] with permissions.
