Photovoltaic research has become increasingly prominent as the search for alternatives to fossil fuels are actively sought. A novel process for the iterative synthesis of discrete donor/acceptor-flanked oligostilbenes, key constituents in dye-sensitized solar cells, is described. The aqueous Wittig process is high yielding, proceeds with high (E)-stereoselectivity and allows facile product purification. (C) 2011 Elsevier Ltd. All rights reserved.
