We report on the approach utilizing poly(glycidyl methacrylate)(PGMA) as a macromolecular anchor for growing of conductive polymers, for example, poly(3-hexyl thiophene)(PHT) on various surfaces: Si-wafer, glass, ITO-modified glass, and various metals (Al, Ti and Au). Our method relies on the deposition of thin strongly adherent PGMA films, followed by a modification with properly functionalised polymerizable compounds and, finally, chemical or electrochemical growing of CPs. This convenient method has the advantage of the modular approach, allowing easy tuning of head-groups thus optimising the polymerisation process and the properties of resulting CP brushes. PHT grafted to glass slides displays solvatochromism similarly to the dissolved PATs. This implies a certain conformational freedom of PHT chains despite the fact that they are tethered to the substrate.
