摘　　要：以Zn(Ⅱ)和2,2′-联吡啶为模板,4-乙烯吡啶为功能单体,三烯丙基异氰脲酸酯为交联剂,采用分子印迹技术,合成了锌离子配位模板聚合物;系统研究了锌离子对聚合物识别的调节作用;平衡结合实验结果表明,乙酸锌(Ⅱ)在一定浓度条件下能显著提高聚合物对2,2′-联吡啶的选择性识别能力。Using Zn_2,2′_dipyridyl complex as template,4_vinylpyridine as the functional monomer and triallyl isocyanurate as the cross_linking monomer,a zinc(Ⅱ)_complex template polymer was prepared by molecularly imprinting technology.The regulation effect of Zn(Ⅱ)to the selective recognition of polymer was studied.The results showed that the ability of selective recognition for2,2′_dipyridyl by the polymer was distinctly enhanced in certain zinc(Ⅱ)acetate solution through equilibrium_binding experiment.
