New organic dyes composed of the benzo[b]furan donor, thiophene-conjugated bridge, and cyano acrylicacid acceptor have been newly synthesized through the one-pot coupling cyclization key step.Nanocrystalline TiO₂ dye-sensitized solar cell was fabricated using this dye. A solar-to-electric conversionefficiency of 6.65% and 4.70% is achieved with 1 and 2, respectively.
