【摘要】 以邻苯二甲酸与乙酸铜的配合物为模板,在甲醇溶剂中制备印迹聚合物,对其色谱保留行为及结构类似物的识别性能进行了研究.结果表明,在甲醇溶液中,该印迹聚合物不仅能够区分模板分子的结构类似物,而且对配合物的金属阴、阳离子都具有很好的识别作用.以邻苯二甲酸为模板制备的聚合物对模板分子本身的保留较弱,但对模板与铜的配合物却表现出了很强的保留值,在此从结构分析的角度给出了解释.更多还原

【Abstract】 Molecularly imprinted polymer（MIP） was synthesized by using the complex of o-phthalic acid-（Cu（Ac）₂） as the template.The experimental results show that （Cu（Ac）₂-o-PA） imprinted polymer[（P（PA/Cu））] has selective binding to its template complex,including selectivities to the anions,cations and（o-PA） analogues of the complex. The possible structure of the complex Cu（Ac）₂-o-PA is also proposed according to the crystal structures of similar systems.According to the results,the acetate in Cu（Ac）₂ also participated the imprinting process and is a part of the template.Therefore,it plays an important role in the recognition of template and its analogue complexes.Additionally,the high retention of o-PA-imprinted polymer[P（PA）] toward Cu（Ac）₂-o-PA and similar Cu-complexes over o-PA itself is well explained by the binding similarity between 4-VP/o-PA and 4-VP/Cu（Ac）₂-o-PA.The metal ion-mediated imprinting approach of present study may find applications for the compound which can not be directly imprinted.更多还原
