Review of molecular imprinting polymer: basic characteristics and removal of phenolic contaminants based on the functionalized cyclodextrin monomer

Abstract

Cyclodextrins (CDs) are formed of starch molecules that are linked together in a cyclic ring. They are composed of five or more (1, 4) connected D-glucopyranoside units. CDs have toroidal, hollow truncated cone structures with exterior hydrophilic edges and internal hydrophobic cavities. The numerous hydroxyl groups available in cyclodextrins are active sites capable of forming various sorts of connections. They can be cross-linked or derived to generate monomers able to form branching or linear networks. Furthermore, they can form inclusion complexes with a variety of guest molecules, including organic and inorganic molecules, thus changing their physicochemical properties, The modification of the imprinting method could produce molecularly imprinted polymers that are stable, dependable, long-lasting, selective, and cost-effective. As a result, molecularly imprinted polymers are becoming increasingly popular in chemical separation and analysis. As found in previous studies, the monomers of cyclodextrins used in molecular imprinting have a higher binding impact on target molecules. The purpose of this study is to highlight the application of imprinting technology utilizing cyclodextrins as a valuable functional monomer in the remediation of phenolic compounds by examining and assessing relevant works published in the literature.

“…89 The MIPs components include templates, functional monomers, solvent, initiator, and cross-linker. 90 They are a class of smart adsorbents created by the directed polymerization of functional monomers around a target molecule (the template), which leaves a particular recognition site once the template is removed. 91 Using synthetic polymers as a basis, the process of molecular imprinting allows for the fabrication of synthetic receptors for a specific target molecule.…”

An Overview on Cyclodextrin and Its Derivatives Encapsulated Inclusion Complex: Preparation Methods and Influencing Factors

“…Differences in the physicochemical features of HP-CD samples that have the same level of substitution generated under different conditions can result from irregularities in the occupancy of hydroxypropyl groups at various locations on the parent CD molecule. Since this purity of CD can have a significant impact on the final quality of the medicinal product and its marketability [32].…”
