Abstract

The solubility of polythiophenes substituted with a hydroxydecyl chain is found to be closely related to the polymerization conditions. The presence of the hydroxy function does not compromise the processability of the polymer into films nor the thermochromic and solvatochromic properties of the materials, although hydrogen bonding between macromolecules is thought to result in the restriction of solubility.
