Enantioselective recognition of mandelic acid with (R)-1,1-bi-2-naphthol-linked calix[4]arene via fluorescence and dynamic light scattering.
A chiral 1,1-bi-2-naphthol-derived calix[4]arene (1) was synthesized via a click reaction. Fluorescence spectra and dynamic light-scattering revealed that Cu(II)-1 complexes were generated in situ and exhibited remarkable enantioselectivity toward mandelic acid. Using this dynamic light-scattering technique, the detection sensitivity was improved almost 100-fold, with a detection limit of 2.0 × 10(-7) M, compared with fluorescent methods.

Design of a novel inherently chiral calix[4]arene for chiral molecular recognition.
A newly designed inherently chiral calix[4]arene was synthesized and resolved to an optically pure form. Enantiomeric recognition ability of the chiral calix[4]arene was examined using 1H NMR experiments with mandelic acid. In addition, the chiral calix[4]arene was applied to asymmetric reactions, as an organocatalyst.

Exceptional chiral recognition of racemic carboxylic acids by calix[4]arenes bearing optically pure alpha,beta-amino alcohol groups.
Calixarenes bearing optically pure alpha,beta-amino alcohol groups at their lower rim exhibit exceptional and efficient chiral recognition ability in discrimination of racemic mandelic acid, 2,3-dibenzoyltartaric acid and 2-hydroxy-3-methylbutyric acid.
