| Abstract | A review. This feature article describes the synthesis of various classes of monomers and polymers incorporating organoiron moieties. Poly-ethers incorporating η6-substituted-arene-η5-cyclopentadienyliron moieties were synthesized via metal-mediated nucleophilic arom. substitution reactions. Linear polymers incorporating both cationic and neutral organoiron units were prepd.; these polymers underwent two electrochem. processes, oxidn. of the neutral iron species occurred between 0.89 and 1.0 V and redn. of the cationic iron groups occurred between -1.10 and -1.45 V. Polynorbornenes, polymethacrylates, and polystyrenes were prepd. via radical and condensation polymn. of organoiron functionalized monomers. The incorporation of azo dyes into the polymers gave rise to a variety of colored materials that could be photobleached in the presence of hydrogen peroxide. The incorporation of benzothiazole-based dyes resulted in colored polymers with higher λmax values than azobenzene-based dyes. Photolytic decoordination of the cationic cyclopentadienyliron moieties resulted in the formation of org. analogs or neutral polyferrocenes depending on the nature of the starting polymers. A no. of 3-arm star-shaped mols. were also prepd.; electrochem. studies showed that the inner and outer iron moieties are reduced at different potentials. [on SciFinder(R)] |
