dc.description.abstract | A phenomenally high molar extinction coefficient heteroleptic ruthenium(l]) complex [Ru(4,4'-carboxylic acid-2,2'bipyridine)(4,4'-(4-{4-methyl-2,5-bis[3-methylbutoxy]styryl)-2,5-bis[3-methylbutoxy}-2,2'-bipyridine)(NCS)(2)] (DCSC13) was synthesized by incorporating donor-acceptor ligands. The absorption spectrum of the DCSC13 sensitizer is dominated by metal-to-ligand charge-transfer transitions (MLCT) in the visible region, with absorption maxima appearing at 442 and 554 nm. The lowest MLCT absorption bands are red-shifted, and the molar extinction coefficients of these bands are significantly higher at 72 100 and 30 600 M-1 cm(-1),respectively, when compared to those of the analogous [Ru(4,4'-carboxylicacid-2,2'-bipyridine)(4,4'-dimethyl-2,2'-bipyridine)(NCS)(2)] (N820) sensitizer. The DCSC13 complex, when anchored on nanocrystalline TiO2 films, exhibited increased short-circuit photocurrent and consequent power-conversion efficiency when compared with the N820 sensitizer. | - |
