Abstract
Polyhydroxy multiple charged ionic compounds that are the reaction product from either a single amidation and aza-Michael addition reaction or a two-step process of synthesizing a gluconamide intermediate and thereafter undergoing an aza-Michael Addition reaction between the gluconamide intermediate and an ionic monomer are disclosed. Methods of making the multiple charged ionic compounds, and uses thereof are also disclosed.
