dc.description.abstract | We synthesized two new terpyridine based Ru sensitizers (SY-01 and SY-02) with the lowest unoccupied molecular orbital (LUMO) levels of these two dyes are well-matched with that of the black dye (N749). Both sensitizers capable of exhibiting metal-to-ligand charge transfer band show a higher molar extinction coefficients (epsilon similar to 5.0-6.8 x 10(3) M-1 cm(-1)) than that (4.2 x 10(3) M-1 cm(-1)) of N749 because of the enhanced absorption arising from thiophene moiety. Density functional theory calculations reveal that LUMOs of SY-01 and SY-02 are distributed over the terpyridine and thienyl moieties. The excited state oxidation potentials, E-ox(o)*, obtained by the electrochemical studies, range from -0.98 to -0.96 V, are sufficiently more negative than the conduction band edge of the TiO2 electrode (ca. -0.5 V). The increased conjugation conferred to SY-01 and SY-02 dyes through Tu-expansion by thiophene moiety increases light-harvesting and energy conversion efficiency in comparison with N749. | - |
