Summary
Methacrylate- and styrene-functionalized monomers substituted with aromatic ether complexes of cyclopentadienyliron were subjected to polymerization using AIBN as the initiator, yielding cationic organoiron polymers. Norbornene-based organoiron monomers were subjected to ring-opening metathesis polymerization reactions to yield the corresponding organoiron polynorbornenes using Grubbs' catalyst. Methacrylate, styrene and norbornene substituted monomers containing chloroarene complexes in their structures were also subjected to nucleophilic aromatic substitution polymerization with dinucleophiles to produce the corresponding polyaromatic ethers and ether-thioethers with acyclic or cyclic olefins in their side chains. These polymers displayed very good solubility in polar solvents at room temperature. Cyclic voltammetric studies revealed that the cationic eighteen-electron iron centers pendent to the polymer side chains underwent reversible reduction processes to produce neutral nineteen-electron species. Further reduction to the anionic twenty-electron iron complexes was also observed. The polyaromatic ethers and ether-thioethers were cross-linked through their olefinic groups, resulting in the isolation of insoluble organoiron networks.
