摘要：

New donor-acceptor type organosilicon polymers were synthesized by the palladium-catalyzed Sono-gashira-coupling reactions of tetrabutyldiethynyldisilane and bis(iodothienyl)benzothiadiazoles. Treatment of the polymers with TiO2 electrodes in chloroform under photochemical or thermal conditions gave the polymer-attached TiO2 electrodes, which were applied to dye-sensitized solar cells with the maximum power conversion efficiency of 0.26%. Hybridization of the polymers with single-walled carbon nanotube was also examined in an attempt to improve the cell performance. (C) 2012 Elsevier B.V. All rights reserved.
