“…23 In our studies, a trimer model of the polymer was used, as the predicted electronic properties showed reasonable convergence when compared to the dimer model. 22,24 The initial geometry of the polymer was created from optimized ferrocene and imidazole fragments. The geometry was then optimized at the B3LYP level of theory using the 6-31G* + SBK mixed basis set that utilizes effective core potential on the Fe atom and the 6-31G* double zeta Pople type basis set on all other atoms.…”

“…21 Cyclic voltammetry and UV-Vis spectra suggested interactions between the ferrocenyl and maleimide moieties. 22 In this paper, we report the synthesis and characterization of copolymers from vinylferrocene and N-vinylimidazole. By incorporating ferrocene into copolymers with imidazole, it was anticipated that electronic interactions may occur between these moieties.…”

Since imidazole is easily protonated and well known to coordinated to various transition metals, its incorporation into a polymer with ferrocene may result in interesting electronic interactions between the ferrocenyl and imidazolium moieties. To this end, copolymers of vinylferrocene and vinylimidazole were prepared in various ratios by free radical polymerization. The interactions between the ferrocenyl and imidazolium moieties were studied by cyclic voltammetry, UV-Vis spectroscopy and density functional theory (DFT) studies. Cyclic voltammetry of polymer thin films showed multiple oxidation waves at low pH or in the presence of Pb 2+ or Cd 2+ ions. The UV-Vis spectrum of thin films showed an additional absorbance at 625 nm suggesting electronic interactions. In addition, DFT studies indicated that the morphology of the polymer would place some of the ferrocenyl and imidazolium moieties in close proximity.
