Dual-channel anchorable organic dyes with a diphenylamine unit as electron donor and acyanoacrylic acid unit as electron acceptor were synthesized and used as sensitizers for dye sensitized solar cells (DSSCs). Two dual-channel anchorable organic dyes which contained two separate light-harvesting units in one molecule. In addition, the corresponding single D-A dye was synthesized for a comparison. Their chemical structures were characterized by 1H-NMR, FT-IR, UV-vis absorption, and MALDI-TOF spectroscopies. Their electrochemical properties were studied by cyclic voltammetric measurement. The ground state geometries of the dyes have been optimized by DFT. The synthesis and characterization of dual-channel anchorable organic dyes with well-defined structure for dye-sensitized solar cells will be presented. |
