Abstract

We report the syntheses of imprinted polymers using iron-oxo-hydroxo clusters as templates. Three new iron clusters, [Fe6O2(OH)2(O2CC(Cl)=CH2)12(H2O)2] (1), [{Fe(O2CC(Cl)=CH2)(OMe)2}10] (2) and [Fe6O2(OH)2(O2C–Ph–(CH)=CH2)12(H2O)2] (3) have been prepared from commercially-available carboxylic acids. Cluster-imprinted-polymers (CIPs) of 1, 2 and 3 were prepared with ethylene glycol dimethacrylate monomer, and of 1 with methyl methacrylate monomer. The imprinted sites within the CIPs were examined using EXAFS and Diffuse Reflectance UV/vis spectroscopy, demonstrating that the clusters 1, 2 and 3 were incorporated intact within the polymers. Extraction of the clusters from the CIPs imprinted with 1 and 3 gave new polymers that showed evidence of an imprinting effect.
