Supramolecular chiral materials based on phenylalanine derivatives, methods of making and using the same

Abstract

The application discloses a kind of supramolecular chiral materials based on phenylalanine derivative and its preparation method and application, belong to supramolecular chemistry field.The application with series halogenated or unhalogenated phenylalanine derivative as first assembly element, with naphthalene amide derivative as second assembly element, with hexafluoroisopropanol as reserve liquid solvent, by the way of water-phase trigger co-assembly, composite supramolecular assembly system is obtained by construction;The substitution effect of halogen atom is used to realize the precise regulation of the helical chiral rotation of assembly, the chiral inversion of supramolecular helical nanostructure is successfully realized, and the series of co-assembly system has excellent chiral optical activity.The preparation process of the co-assembly system described in the application is simple, the chiral rotation is accurately controlled, the product structure has excellent stability, and has wide application prospect in the fields of supramolecular chiral material, chiral sensor, chiral recognition and separation.
