Poly[(ethoxyhexylsilylene)quarter-and-quinquethienylene]s (EHSxT, x = 4 and 5) were prepared by Stille-coupling reactions of bis(bromothienyl)ethoxyhexylsilane and bis(tributylstannyl)di-and-terthiophenes, respectively. Treatment of ITO and TiO 2 electrodes with solutions of EHSxT in chloroform at 40°C led to the formation of the polymer-attached electrodes. An application of the EHS5T-attached TiO 2 electrode to dye-sensitized solar cell was examined.
