以1-甲基-2,4-二(N’-十八烷脲基)苯为凝胶剂,以液体单体丙烯酸-2-乙基己酯、甲基丙烯酸甲酯、二甲基丙烯酸聚乙二醇(200)酯以及模板分子和光敏引发剂的混合物为溶剂,其目的是利用该凝胶剂可在这个混合物中进行超分子自组装,形成互相缠绕的具有纳米尺寸的纤维状聚集体,并最终导致这些单体混合物形成稳定的超分子有机凝胶.然后经UV光引发聚合,经乙醇抽提凝胶剂聚集体和模板分子,制备了一种新型分子印迹的聚合有机凝胶膜材料.探讨了不同凝胶剂浓度、模板分子浓度、单体混合物配比所制备的印迹聚合有机凝胶膜对D-和L-苯丙氨酸吸附效率的影响.结果表明所制备的印迹聚合有机凝胶膜对L-苯丙氨酸吸附效率约为对D-苯丙氨酸吸附效率的3～4倍,表现出明显的选择性吸附性.
Using 1-methyl-2,4-bis (N’-octadecylureido) benzene as the gelling agent and liquid monomer 2-ethylhexyl acrylate, methyl methacrylate and dimethacrylic acid Polyethylene glycol (200) and a mixture of the template molecule and the photoinitiator are used as a solvent for the purpose of utilizing this gellant to perform supramolecular self-assembly in this mixture to form a coiled, nanofiber-sized, fibrous aggregate And eventually led to the formation of stable supramolecular organogels by these monomer mixtures.Then the polymerization was initiated by UV light and the gel aggregates and template molecules were extracted by ethanol to prepare a new molecularly imprinted polymeric organogel The effects of different gel concentration, template concentration and monomer mixture ratio on the adsorption efficiency of D- and L-phenylalanine were investigated.The results showed that the prepared imprinted Polymerization of organic gel film L-phenylalanine adsorption efficiency of about D-phenylalanine adsorption efficiency of 3 to 4 times, showing significant selective adsorption.
