Abstract
The invention is related to a process for preparing polythiophenes. The polythiophenes are prepared by oxidatively polymerizing a thiophene or thiophene derivative with an oxidizing agent, wherein the oxidizing agent used is at least one hypervalent iodine compound. The invention further relates to a process for producing dispersions and a process for producing conductive layers.

A process for preparing polythiophenes which comprises oxidatively polymerizing a thiophene or thiophene derivative with an oxidizing agent, wherein the oxidizing agent used is at least one hypervalent iodine compound.
A process for preparing dispersions comprising optionally substituted polythiophenes by oxidatively polymerizing optionally substituted thiophene or thiophene derivative in the presence of at least one solvent and optionally of at least one counterion, wherein the oxidizing agent used is at least one hypervalent iodine compound.
A process for producing a conductive layer comprising optionally substituted polythiophenes, wherein optionally substituted thiophene or thiophene derivative is oxidatively polymerized on a suitable substrate with at least one hypervalent iodine compound as an oxidizing agent in the presence or absence of at least one solvent.
