原位分子印迹法制备的连续棒型模板聚合物的手性识别

使用Ｒ－１－（１－萘基）乙胺为模板分子，α－甲基丙烯酸为功能单体，乙二醇二甲基丙烯酸酯为交联剂，采用原位分子印迹分子制备了具有手性识别环境的连续棒型模板聚合物。色谱结果表明，这种连续棒型模板聚合物对模板分子Ｒ－１－（１－萘基）乙胺比对它的对映异构体Ｓ－１－（１－萘基）乙胺及其外消旋体具有更长的保留时间，更大的容量因子，展现了一定的手性识别能力。

Enantiomeric Recognition of Continuous Molecularly Imprinted Polymer Rod Prepared by In-situ Method

A continuous rod of molecularly imprinted polymer was prepared by in situ molecular imprinting technique using R-1-(1-naphthyl) ethylamine as template molecules. The preparation procedure was simple and easy. The enantiomeric recognition of the moecularly imprinted polymer rod was evaluated hy comparing the retention values of the enanhomers of 1-(1-naphthyl)ethylthene and its mcemate in liquid chromatography. The results showed that the original template was more strongly retained than its isomer and racemate in the imprinted polymer rod-type coltumn. However, a blank polymer rod with the same chemical composition could not retain any antipode of 1-(1-naphthyl)ethylamine. This suggested that the template was effectively .imprinted in the prepared polymer rod by the in-situ method.
