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.

Poly (N-alkylcarbazole) columnar structure and method for producing the same

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.

Method for chemically producing poly(N-alkylcarbazole) columnar structure

There is provided a composition for electrochromic devices which clearly present only two states, a white-colored state and a decolored state. The composition for electrochromic devices contains (A) a specific quaternary ammonium salt, (B) a supporting electrolyte containing bromide ion, and (C) a solvent containing water as an essential component, and (A) is soluble in (C).
