CD studies were performed on the enantiomeric recognition of chiral aralkyl ammonium salts 1-3 by chiral pyridino-18-crown-6 ligands 4 and 6. Heterochiral complexing was found to result in larger spectral effects in both the 1 L b and 1 L a band regions of the chiral crown ethers. Based on the resul
