Abstract

A poly(N-alkylcarbazole) columnar structure having electroconductivity is provided. The poly(N-alkylcarbazole) columnar structure having electroconductivity may be produced by electrolytically polymerizing an N-alkylcarbazole in a particular solvent.

Claims (15)

1. A poly(N-alkylcarbazole) columnar structure.

2. The poly(N-alkylcarbazole) columnar structure according to claim 1 , wherein the columnar structure has a diameter of from 0.1 to 10 μm.

3. A poly(N-alkylcarbazole) columnar structure according to claim 1 , wherein the columnar structure is formed by electrolytically polymerizing an N-alkylcarbazole in an alcohol solvent,

wherein electrolytically polymerizing the N-alkylcarbazole involves applying a voltage between a working electrode and a counter electrode of from +0.5 to +3.0 V with respect to a reference electrode or applying a voltage between an anode and a cathode of from +0.9 to +4.0 V when the reference electrode is not used.

4. The poly(N-alkylcarbazole) columnar structure according to claim 3 , wherein the alcohol solvent contains from 1 mM to 10 M of a supporting electrolyte.

5. The poly(N-alkylcarbazole) columnar structure according to claim 4 , wherein the supporting electrolyte is tetrabutylammonium perchlorate.

6. The poly(N-alkylcarbazole) columnar structure according to claim 1 , wherein the columnar structure is a hollow columnar structure.

7. A method for producing a poly(N-alkylcarbazole) columnar structure by polymerizing an N-alkylcarbazole, the method comprising electrolytically polymerizing the N-alkylcarbazole in an alcohol solvent containing a supporting electrolyte,

wherein electrolytically polymerizing the N-alkylcarbazole involves applying a voltage between a working electrode and a counter electrode of from +0.5 to +3.0 V with respect to a reference electrode or applying a voltage between an anode and a cathode of from +0.9 to +4.0 V when the reference electrode is not used.

8. The poly(N-alkylcarbazole) columnar structure according to claim 2 , wherein the columnar structure is a hollow columnar structure.

9. The poly(N-alkylcarbazole) columnar structure according to claim 3 , wherein the columnar structure is a hollow columnar structure.

10. The poly(N-alkylcarbazole) columnar structure according to claim 4 , wherein the columnar structure is a hollow columnar structure.

11. The poly(N-alkylcarbazole) columnar structure according to claim 5 , wherein the columnar structure is a hollow columnar structure.

12. The poly(N-alkylcarbazole) columnar structure according to claim 1 , wherein the columnar structure is in the form selected from a cylindrical column and a polygonal column.

13. The poly(N-alkylcarbazole) columnar structure according to claim 1 , wherein the columnar structure has a length of 1 μm or more.
