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), 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
