Natural cyclodextrins and their derivatives for polymer synthesis

Cyclodextrins (CDs) are a family of cyclic oligosaccharides with a hydrophilic exterior surface and a nonpolar cavity interior, therefore, CDs can form inclusion complexes through noncovalent interactions with a broad range of hydrophobic guests. CD derivatives and CD-based polymers find important uses in different fields such as pharmacy, cosmetics, biomedicine, textiles, and food domain due to their unique properties during the past decade. Hence, in this review, functionalised CDs and CD-based polymers are classified and discussed according to their synthetic approaches comprehensively to help polymer chemists for the development of new CD-based materials for different types of applications.
