Study on Characteristics of Molecular Recognition of Metalcomplexing Template Polymer

Zhou Jie , He Xiwen, Shi Huiming(Department of Chemistry, Nankai University,Tianjin,300071)  
Using cobalt()diphenadione complex as template, 4vinylpyridine as the functional monomer and ethylene glycol dimethacrylate as the crosslinking monomer, a new kind of metalcomplexing template polymer which has the binding sites analous to metalchelate antibody was prepared by molecular imprinting technique.Its characteristics of specificially and selectively binding to diphenadione by matal ion mediated recognition in the polymer was studied in detail.The results of equilibrium binding experiments showed that the selective recognition of diphenadione by the polymer was distinctly enhanced at the optimum concentration of cobalt() acetate, as compared with the two control polymers with the same chemical composition as it. It is possible to be used in the enviromental and medical studies.
