An assembled hematin is formed by depositing hematin on an electrically charged substrate in one or more layers alternating with one or more layers of polyelectrolyte, preferably a cationic polymer. In a method for polymerizing an aromatic monomer, the assembled hematin is contacted with the monomer and a template, preferably an anionic polymer. In a method for polymerizing aniline, the aniline, sulfonated multi walled carbon nano tubes, PEG hematin and a reaction initiator are dispersed in water.

Assembled hematin, method for forming same and method for polymerizing aromatic monomers using same

Antioxidant polymers of the present invention comprise repeat units that include one or both of Structural Formulas (I) and (II): wherein:

Hematin, a hydroxyferriprotoporphyrin, is derivatized with one or more non-proteinaceous amphipathic groups. The derivatized hematin can serve as a mimic of horseradish peroxidase in polymerizing aromatic monomers, such as aromatic compounds. These derivatized hematins can also be used as catalysts in polymerizing aromatic monomers, and can exhibit significantly greater catalytic activity than underivatized hematin in acidic solutions. In one embodiment, polymerization is in the presence of a template, along which aromatic monomers align. An assembled hematin includes alternating layers of hematin and a polyelectrolyte, which are deposited on an electrically charged substrate. Assembled hematin can also be used to polymerize aromatic monomers.
