Abstract
The present invention relates to a method for manufacturing a water-soluble n-type conducting polymer, the method comprising the steps of: a) adding a monomer to a solvent system comprising water in the presence of a catalyst, thus providing a reaction solution; b) allowing the monomer to polymerize in the reaction solution thus obtaining an n-type conducting polymer solution; c) post-treating the n-type conducting polymer solution thus obtaining a water-soluble n-type conducting polymer.
