Acrylamide (AM) was copolymerized with ethylene glycol dimethacrylate (EGDMA) in the presence of (R)-1,1'-binaphthalene-2-naphthol (BINOL) as the template molecules on the surface of silica gel by a free radical polymerization to produce a chiral stationary phase based on the surface molecularly imprinted polymer (SMIP-CSP). The SMIP-CSP showed a much better separation factor (α = 4.28) than the CSP based on the molecularly imprinted polymer (MIP-CSP) without coating on the silica gel (α = 1.96) during the chiral separation of BINOL enantiomers by high-performance liquid chromatography. The influence of the pretreatment temperature and the content of the template molecule ((R)-BINOL) of the SMIP-CSP, and the mobile phase composition on the separation of the racemic BINOL were systematically investigated.
在硅胶表面，以（R）-1,1'-联萘-2-萘酚（BINOL）为模板分子，通过自由基聚合使丙烯酰胺（AM）与乙二醇二甲基丙烯酸酯（EGDMA）共聚，制备基于表面分子印迹聚合物（SMIP-CSP）的手性固定相。在高效液相色谱法对手性BINOL对映体进行手性分离过程中，SMIP-CSP表现出比未涂覆在硅胶上的基于分子印迹聚合物的固定相（MIP-CSP）更好的分离因子（α = 4.28）（α = 1.96）。系统研究了SMIP-CSP的预处理温度、模板分子（（R）-BINOL）含量以及流动相组成对外消旋BINOL分离的影响。
