Transfer of chiral information through achiral ion recognition by a novel pseudocrown ether with a binaphthyl moiety

Abstract

A significant enhancement in the proportion of the (P)-helical enantiome (see picture) of the tetrahedral copper(I) - bipyridine units in a chiral pseudocrown ether occurs on complexation with an achiral alkali metal ion (M+). This dually responding system also works as an AND device for CD output by utilizing coordination and chiral information, with the Cu+ and Na+ ions acting as the input signals.
