An acidic 22/35 mM sodium/phosphate background electrolyte, pH 2.4, with addition of randomly sulfated alpha-, beta- and gamma-cyclodextrins-based chiral selectors allowed enantioresolution of a series of helquats, which comprised 5, 6 and 7 fused rings participating in the helical backbone. In general, at least one of the chiral selectors provided a baseline separation for 22 out of 24 helquats and partial separation for the remaining two.
