Title:
POLYTHIOPHENE STAR COPOLYMER CAPABLE OF BEING SELF-DOPED BY AN EXTERNAL STIMULUS, A METHOD FOR PRODUCING THE SAME, A CONDUCTIVE THIN FILM USING THE SAME, AND A METHOD FOR PRODUCING THE CONDUCTIVE THIN FILM
Document Type and Number:
WIPO Patent Application WO/2013/157741
Kind Code:
A1
Abstract:
The present invention provides a method for producing polythiophene star copolymer capable of being self-doped by an external stimulus, which includes the steps of: forming a polythiophene macroinitiator made by introducing a living radical polymerizable functional group into an end of polythiophene or a derivative thereof; forming through living radical polymerization a polymer macroinitiator for providing by an external stimulus at least a dopant selected from the group consisting of sulfonic acid radical, carboxylic acid radical and phosphoric acid radical; and polymerizing the polythiophene macroinitiator added with the polymer macroinitiator and at least one kind of divinyl monomer to produce the polythiophene star copolymer. The polythiophene star copolymer capable of being self-doped by an external stimulus according to the present invention is a self-doped material to stably increase conductivity, and can be used as a material for a conductive film.
