Abstract:

With the rapid development of chromatographic stationary-phase preparation technology, various modified methods are becoming increasingly mature, mainly including direct surface chemical reactions, agglomeration, grafting, and hyperbranched modification. Among these methods, hyperbranched modification based on polycondensation has been popular with researchers since it was proposed, and it has been applied to the preparation of various anion exchangers. Dendrimers are a class of three-dimensional, highly ordered dendritic macromolecules with perfect structure, high degree of surface functionality, and unique physicochemical properties. Recently, they have also gradually been applied in various chromatographic stationary-phase modifications and are expected to improve the structure and separation performance of the stationary phase, because its structure is similar to those of hyperbranched polymers. This article mainly summarizes the applications of hyperbranched and poly amidoamine dendrimers using grafted modification methods in the preparation of the chromatographic stationary phase. Finally, the trends and promising prospects of this field are presented.
