Title:
POLYTHIOPHENE POLYMERIZATION CATALYST, AND METHOD FOR PRODUCING POLY(SUBSTITUTED THIOPHENE)
Document Type and Number:
WIPO Patent Application WO/2012/014844
Kind Code:
A1
Abstract:
Disclosed is a catalyst that uses low-cost materials, has an easy production step, has no particular need to control reaction temperature at a low-temperature region, and enables the production of a poly(substituted thiophene) at a yield that is at least equivalent to that of conventional methods for producing a poly(substituted thiophene) and having an excellent molecular weight distribution and stereoregularity that are at least equivalent to those of a poly(substituted thiophene) produced by means of said conventional methods. The polythiophene polymerization catalyst contains the belowmentioned 1 as well as 2 and/or 3: (1) a base obtained by reacting a primary or secondary amine with a Grignard reagent/alkali metal halide complex; (2) a nickel catalyst; and (3) a palladium catalyst.
