Abstract

A method for producing a transparent electroconductive material, the method comprising a step of contacting poly(N-alkylcarbazole) with a metal, said poly(N-alkylcarbazole) is obtained by polymerizing at least one kind of N-alkylcarbazole represented by the following general formula, wherein n represents an integer of 1 or more, and at least one hydrogen in the alkyl may be replaced by at least one group selected from hydroxyl, carboxyl, sulfo and amino.

Claims (14)

1 . A method for producing a transparent electroconductive material, the method comprising a step of contacting poly(N-alkylcarbazole) with a metal, said poly(N-alkylcarbazole) is obtained by polymerizing at least one kind of N-alkylcarbazole represented by the following general formula,

wherein n represents an integer of 1 or more, and at least one hydrogen in the alkyl may be replaced by at least one group selected from hydroxyl, carboxyl, sulfo and amino.

2 . The method for producing a transparent electroconductive material according to claim 1 , wherein the step of contacting poly(N-alkylcarbazole) with a metal is performed in a liquid phase.

3 . The method for producing a transparent electroconductive material according to claim 1 , wherein the metal used in the step of contacting poly(N-alkylcarbazole) with a metal is a molten metal.

4 . The method for producing a transparent electroconductive material according to claim 1 , wherein poly(N-alkylcarbazole) is obtained by chemical polymerization.

5 . A transparent electroconductive material produced by the method according to claim 1 .

6 . A method for producing an ink for forming a transparent electroconductive material, the method comprising the steps of:

a) dissolving poly(N-alkylcarbazole) in a solvent to form a poly(N-alkylcarbazole) solution, said poly(N-alkylcarbazole) is obtained by polymerizing at least one kind of N-alkylcarbazole represented by the following general formula,

wherein n represents an integer of 1 or more, and at least one hydrogen in the alkyl may be replaced by at least one group selected from hydroxyl, carboxyl, sulfo and amino; and

b) contacting said solution with a metal.

7 . A method for producing an ink for forming a transparent electroconductive material, the method comprising a step of contacting a poly(N-alkylcarbazole) solution with a metal, said poly (N-alkylcarbazole) solution is obtained by chemical polymerization of at least one kind of N-alkylcarbazole represented by the following general formula in a solvent,

wherein n represents an integer of 1 or more, and at least one hydrogen in the alkyl may be replaced by at least one group selected from hydroxyl, carboxyl, sulfo and amino.

8 . The method for producing an ink for forming a transparent electroconductive material according to claim 6 , wherein poly(N-alkylcarbazole) is obtained by chemical polymerization.

9 . An ink for forming a transparent electroconductive material produced by the method according to claim 6 .
