Chiral Recognition of α-Amino Acid Derivatives by a Steroidal Crown Ether at the Air-Water Interface

Abstract
4′-(Cholesteryloxycarbonyl)benzo-18-crown-6 forms a stable monolayer at the air-water interface and the π-A isotherms respond to α-amino acid derivatives in an asymmetric manner. This is a novel amino acid sensing system using a monolayer assembly.
