-CD) not only can form inclusion complexes with the other compounds because of the cavity of CD
but also can increase the hydrogen-bonding
electrostatic and dipole-dipole interactions between hosts and guests due to the presence of carboxymethyl. Functional materials with excellent properties can be prepared by modifying CM-
β
-CD
and these materials have been widely used in pharmaceuticals
separation
biological sciences
environmental protection and wastewater treatment. This paper analyzed the properties of CM-
β
-CD and reviewed the preparation of CM-
β
-CD functional materials
such as CM-
β
-CD polymers
composites and modified biomolecules in recent years. The adsorption of CM-
β
-CD functional materials for organic molecules
biomolecules and metal iones were also summarized. Moreover
the development of CM-
β
-CD functional materials was prospected and some suggestions were proposed.
