    Study on the Synthesis and Properties of S -Naproxen Molecularly Imprinted Polymers Using N-vinylpyrrolidone as a Functional Monomer

    • 摘要: 以S-萘普生为模板,N-乙烯基吡咯烷酮为功能单体,二乙烯基苯为交联剂分别按照摩尔比1/4/10、1/4/20和1/4/30合成了分子印迹聚合物(MIP)。采用UV和Chem 3D Pro软件计算模拟研究了功能单体与模板分子之间的相互作用,经半经验量化PM3方法计算得到功能单体与模板分子之间的相互作用能为-20.97 kJ/mol。探讨了交联度对MIP吸附性能和识别能力的影响,结果表明在所研究的O~4mmol/L浓度范围内,MIP对S-萘普生的结合量随着交联度的增加而减小,而交联度为88%的印迹聚合物P3对S-萘普生和阿司匹林的分离因子为2.70,交联度为83%的聚合物P2的分离因子为2.60,交联度为71%的聚合物P1的分离因子为1.44,即高交联度MIP的识别能力优于低交联度的。

       

      Abstract: Molecularly imprinted polymers were prepared using S-naproxen as a template molecule, N-vinylpyrrolidone as a functional monomer and divinylbenzene as a crosslinker. By means of UV spectroscopy and computational approach, the interaction between template
