Two porphyrin-based dyes were synthesized that incorporate two additional chromophores to absorb in a wider UV/Vis region. In the first dye, a porphyrin ring is linked through an amide bond to two [Ru(bpy)(3)](2+) units, forming a symmetric [Ru(bpy)(3)]-porphyrin-[Ru(bpy)(3)] {Por(COOH)(2)[Ru(bpy)(3)](2)} system. The second porphyrin is trans substituted through a triple bond to the meso position with two boron dipyrrin (BDP) molecules {Por(COOH)(2)(BDP)(2)}. Both porphyrins bear two carboxylic groups capable of binding onto a TiO2 surface, with potential applications in dye-sensitized solar cells (DSSCs). The title dyes were characterized by means of H-1 and C-13 NMR spectroscopy, elemental analysis, MALDI-TOF, UV/Vis absorption and emission studies.
