We have designed and synthesized novel zinc porphyrin dyes that have D-π-A system based on porphyrin derivatives containing various electron-donating group and a meso-substituted phenyl cyanoacrylic acid anchoring group attached at the meso position of the porphyrin ring, yielding the push-pull porphyrins as the most efficient green dye for DSSCs applications. Their chemical structures were characterized by 1H-NMR, FT-IR, UV-vis absorption, and MALDI-TOF mass spectroscopy. These novel Zn(II)-porphyrin dyes have been used to fabricate dye-sensitized solar cells based on liquid electrolytes as dye sensitizers. Here, their synthesis, characterization and DSSC performance will be described. |
