Abstract

A method for polymerizing electronic and photonic polymers, wherein an aromatic monomer is combined with a hematin catalyst derivatized with at least one non-proteinaceous amphipathic group, and a peroxide initiator, and employing a template, wherein the aromatic monomer aligns along the template and polymerizes to form a complex comprising the polymerized monomer and the template.

Claims

1. A method for the synthesis of a conducting polymer, the method comprising the steps of

dissolving polystyrene sulfonate in deionized water at a pH of 1.0–

2.0 to produce a solution;

adding a monomer, said monomer being selected from the group comprising aniline and pyrrole, to the solution;

adding polyethylene glycol-hematin to the solution;

adding hydrogen peroxide in small increments to the solution;

stirring the solution to complete the synthesis of the conducting polymer;

effecting dialysis of the synthesized conducting polymer; and

drying the conducting polymer under a vacuum.

2. The method in accordance with claim 1 wherein the dried conducting polymer exhibits a gravimetric yield of at least about 95%.
