The SAMs on ITO was prepared using Ru(4,4'-dicarboxylic acid-2,2'-bipyridine)(2)(NCS)(2) and di(3-aminopropyl)viologen. The photoelectrochemically polymerized polythiophene layers on SAMs/ITO were characterized using UV-vis. absorption spectroscopy, atomic force microscopy, scanning electron microscopy, and cyclic voltammetry. The polymer layers have thickness of similar to 360 nm, a dense surface morphology, optical gap of 2.38 eV, highest occupied molecular orbital of -5.2 eV and lowest unoccupied molecular orbital of -2.82 eV. In photoelectrochemical cells, the polythiophene on SAMs/ITO electrode showed a photocurrent of 5 mu A/cm(2).
