Imprinted polymeric materials. insight into the nature of prepolymerization complexes of quercetin imprinted polymers
2006
Molecular imprinting techniques have proved to be a highly accessible method for producing molecule-specific recognition materials for a variety of applications, ranging from sensing to catalysis and separations. In noncovalent imprinting, it is anticipated that polymerizable complexes are created in the prepolymerization solution via self-assembly of functional monomers and template molecules resulting from inherent chemical complementarity, which will ideally form binding sites within the cross-linked matrix after polymerization. On the basis of 1H NMR data and X-ray crystallographic evidence, we now infer a more important role for template self-association for the recognition properties of quercetin-imprinted polymers. While directly applicable to fundamental understanding of the molecular imprinting mechanism of this polyphenol, on a more generic scale, this work also demonstrates the utility of this strategy toward analyzing complex noncovalent interaction mechanisms between small molecules. These in...
