Abstract

Chirality transcription and amplification by the formation of chiral [2]pseudorotaxanes by an achiral crown ether having the 2′,2′′-quaterphenyl group and chiral sec-ammonium ions are reported. It was revealed that the absolute configurations of the chiral sec-ammonium ions can be detected directly from the CD spectra of the chiral [2]pseudorotaxanes.
