Claims
- 1. A method for preparing a water-soluble, chiral conducting polymer complex which comprises the steps of:(a) adding a monomer of the conducting polymer to a solution of a water-soluble polymer such that a water-soluble adduct is formed; (b) adding a chiral compound to the solution of the soluble adduct; and (c) polymerizing the monomer, whereby a chiral inter-polymer complex is formed.
- 2. The method as described in claim 1, wherein the water-soluble polymer comprises a neutral water-soluble polymer.
- 3. The method as described in claim 2, wherein the neutral water-soluble polymer is selected from the group consisting of polyvinylpyrrolidone, polyacrylamide, polyvinyl alcohol.
- 4. The method as described in claim 1, wherein the water-soluble polymer comprises a polyelectrolyte.
- 5. The method as described in claim 4, wherein the polyelectrolyte is selected from the group consisting of polyacrylic acid, polystyrene sulphonic acid, and polyvinylsulphonic acid.
- 6. The method as described in claim 1, wherein the water-soluble polymer comprises biopolymers.
- 7. The method as described in claim 6, wherein the biopolymers are selected from the group consisting of hydroxyethyl cellulose, proteins, DNA, RNA, and polysaccharides.
- 8. The method as described in claim 1, wherein the water-soluble polymer comprises inorganic polymers.
- 9. The method as described in claim 8, wherein the inorganic polymers comprise polyphosphates.
- 10. The method as described in claim 1, wherein the monomers comprise conducting polymer monomers and derivatives thereof.
- 11. The method as described in claim 10, wherein the monomers are selected from the group consisting of aniline, pyrrole, thiophene, phenylene, acetylene, etc. which polymerize to yield polythiophene, polyphenylene, and polyacetylene and derivatives thereof.
- 12. The method as described in claim 1, wherein the chiral compound comprises a chiral acid.
- 13. The method as described in claim 12, wherein the chiral acid is selected from the group consisting of (±)-CSA, D-tartaric acid and L-tartaric acid.
- 14. The method as described in claim 1, wherein said step of polymerization is performed by adding an oxidant to the solution selected from the group consisting of sodium persulfate, ammonium persulfate, hydrogen peroxide, ferric chloride, and cerium chloride.
