摘要
Novel pi-extended squarylium dyes with dicyanovinylene substitution were synthesized through the Stille-type Pd-catalyzed cross-coupling reaction of a precursory iodinated squarylium dye with tributylstannyl squarate. Dye-sensitized solar cells (DSSCs) based on the squarylium dyes displayed remarkable performances in a wide wavelength range from the visible to the near-infrared region around 800 nm. The power conversion efficiencies of the DSSCs based on In-CN-In-S-OH and In-CN-In-S-In-COOH reached 3.5% and 2.1%, respectively.
