  • Poly (N-alkylcarbazole) columnar structure and method for producing the same
    Patent number: 8629225
    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.
    Type: Grant
    Filed: March 4, 2011
    Date of Patent: January 14, 2014
    Assignees: National University Corporation Chiba University, JNC Corporation
    Inventors: Katsuyoshi Hoshino, Kazuki Takizawa, Katsuyuki Murashiro, Toshiki Komatsu
  • Method for chemically producing poly(N-alkylcarbazole) columnar structure
    Patent number: 8609796
    Abstract: A novel nanosized or microsized material having electroconductivity that can be produced simply and in a large amount is provided. A method for producing a poly(N-alkylcarbazole) columnar structure having electroconductivity obtained by chemically polymerizing N-alkylcarbazole including alkyl having 1 to 4 carbons by adding an oxidizing agent to a solution obtained by dissolving the N-alkylcarbazole in a solvent is provided.
    Type: Grant
    Filed: June 14, 2012
    Date of Patent: December 17, 2013
