杯芳烃衍生物和丙烯酰胺作为复合功能单体的分子印迹聚合物对海因类化合物的选择性识别研究

以杯4]芳烃衍生物+丙烯酰胺作为复合功能单体,将其运用到分子印迹技术中,对海因类化合物R-苄基海因进行选择性识别.研究结果表明,由单一的杯4]芳烃衍生物或丙烯酰胺作为功能单体的分子印迹聚合物对R-苄基海因的选择性均不高,而由杯4]芳烃衍生物+丙烯酰胺作为复合功能单体的分子印迹聚合物对模板分子具有较高的特异选择性.

Molecularly Imprinted Polymer with Bi-functional Monomers of Calix Arene Derivative and Acrylamide for Selective Recognition of Hydantoin-based Compounds

Using calix \ arene derivative and acrylamide(AM) as the bi-functional monomers and 5-benzylhydantoin(R-BZH) as a template,a molecularly imprinted polymer was prepared to recognize hydantoin-based compounds selectively.The results of equilibrium binding experiments indicate that the selectivity of the MIP,which is synthesized with a single functional monomer(calix \ arene derivative or acrylamide),is poor;while the selectivity of another MIP,which is synthesized with two functional monomers(both calix \ arene derivative and AM),showed higher and better selective recognition abilities for R-BZH. It was entirely possible to separate and enrich R-BZH from hydantoin-based compounds by molecularly imprinting technique.
