摘要:以丙烯酸为功能单体,二苯甲酰 L 酒石酸(L DBTA)为模板分子,三羟甲基丙烷三丙烯酸酯(TMPTA)为交联剂,采用光聚合方法合成了 L DBTA手性分子印迹聚合物,讨论了功能单体种类、功能单体用量、交联剂用量、引发剂用量、三乙胺用量、光聚合温度、光聚合时间、光强度等对L DBTA手性分子印迹聚合物合成的影响。通过L DBTA手性分子印迹聚合物对底物的结合实验分析,表明手性分子印迹聚合物对L DBTA具有很好的识别性, L DBTA的选择性比二苯甲酰 D 酒石酸(D DBTA)高,其分离因子可达5.41。
Using a functional monomer(methyl methacrylate, acrylamide, ethyl acrylate or acrylic acid) and a crosslinker(TMPTA), molecularly imprinted polymers(MIPs) with recognition properties to dibenzoyl-L-tartaric acid(L-DBTA) were prepared by photopo-polymerization method in the presence of a template(L-DBTA) in acetonitrile solution.The experimental results indicated that the MIPs had higher L-DBTA binding ability than D-DBTA′s and also higher than corresponding non-imprinted polymers. The binding ability of MIPs is the highest at template (n_(L-DBTA)/n_(AA)/n_(TMPTA)= 1/4/12 as photo-polymerization time was 1.5h and photopolymering in a ice-water bath under a 100W ultraviolet lamp about 0.07m. Based on the optimal experimental results, it was found that the highest separation factor (α) of L-DBTA/D-DBTA of the MIPs could reach to be 5.41.
