在[BMIM][BF 4]基绿色溶剂中使用高含量单体的策略成功地获得了具有良好渗透性的MIP整体柱。以酮洛芬或萘普生为模板分子，4-乙烯基吡啶为功能单体，乙二醇二甲基丙烯酸酯为交联单体，制备了分子印迹整体柱。MIP整体柱的柱效和渗透性可以通过[BMIM][BF 4]/DMSO的混合物来调节。该方法允许在短的聚合时间（<1.5 h）和更高的印迹因子（8.64）比在传统的挥发性溶剂中制备的MIP的创建印迹系统。研究了高单体含量的MIP整体材料的结构和形态，如中值孔径、孔体积和孔径分布。考察了模板剂与功能单体的比例、共聚单体与功能单体的比例等聚合参数对聚合物柱性能的影响。
A MIP monolith with good permeability was successfully achieved using a strategy involving a high content of monomers in a [BMIM][BF4]-based green solvent. The imprinted monolith was prepared with ketoprofen or naproxen as a template, 4-vinylpyridine as the functional monomer, and ethylene glycol dimethacrylate as a crosslinking monomer. Column efficiency and permeability of the MIP monolith can be tuned by a mixture of [BMIM][BF4]/DMSO. The approach allowed the creation of an imprinting system in a short polymerization time (<1.5 h) and higher imprinting factor (8.64) than the MIP prepared in a traditional volatile solvent. The texture and morphology of the MIP monoliths with a high content of monomers, such as median pore diameter, pore volumes, and pore size distributions, were studied. The influence of polymerization parameters, such as the ratio of template to functional monomer, and the ratio of comonomer to functional monomer on the column performance of the resultant MIP was also investigated.
