Two click binaphthyl chiral stationary phases were synthesized and evaluated by liquid chromatog. Their structures incorporate S-(-)-1,1′-binaphthyl moiety as the chiral selector and 1,2,3-triazole ring as the spacer. These chiral stationary phases (CSPs) allowed the efficient resolution for a wide range of racemic BINOL derivatives, particularly for nonpolar diether derivatives and 3-Ph indolin-2-one analogs. The chromatog. data showed that the π-π interaction was crucial for enantiorecognition of these CSPs. Loss of enantioselectivity observed on CSP3, which are lacking the triazole ring linkage, indicated that the triazole ring linkage took part in the enantioseparation process, although it was remote from the chiral selector of the CSP. The substitution of the Ph group at 6 and 6′ positions can significantly improve the separation ability of the CSP. The chiral recognition mechanism was also studied by tracking the elution orders and studying the thermodn. parameters. Chirality 00:000-000, 2012. Copyright © 2012 Wiley Periodicals, Inc.
