| 摘 要： | Amphiphilic polypyridyl mthenium（Ⅱ） complex cis-di（isothiocyanato）（4,4＇-di-tert-butyl-2,2＇-bipyridyl）（4,4＇- dicarboxy-2,2＇-bipyridyl）ruthenium（Ⅱ）（K005） has been synthesized and characterized by cyclic voltammetry, ^1H NMR, UV-Vis, and FT-IR spectroscopies. The sensitizer sensitizes TiO2 over a notably broad spectral range due to its intense metal-to-ligand charge-transfer （MLCT） bands at 537 and 418 nm. The photophysical and photochemical studies of K005 were contrasted with those of cis-Ru（dcbpy）2（NCS）2, known as the N3 dye, and the amphiphilic ruthenium（Ⅱ） dye Z907. A reversible couple at E1/2=0.725 V vs. saturated calomel electrode （SCE） with a separation of 0.08 V between the anodic and cathodic peaks, was observed due to the Ru^Ⅱ/Ⅲ couple by cyclic voltammetry. Furthermore, this amphiphilic ruthenium complex was successfully used as sensitizers for dye-sensitized solar cells with the efficiency of 3.72% at the 100 mW·cm^-2 irradiance of air mass 1.5 simulated sunlight without optimization of TiO2 films and the electrolyte.

| Abstract: | Amphiphilic polypyridyl ruthenium(II) complex cis‐di(isothiocyanato)(4,4′‐di‐tert‐butyl‐2,2′‐bipyridyl)(4,4′‐ dicarboxy‐2,2′‐bipyridyl)ruthenium(II) (K005) has been synthesized and characterized by cyclic voltammetry, 1H NMR, UV‐Vis, and FT‐IR spectroscopies. The sensitizer sensitizes TiO2 over a notably broad spectral range due to its intense metal‐to‐ligand charge‐transfer (MLCT) bands at 537 and 418 nm. The photophysical and photochemical studies of K005 were contrasted with those of cis‐Ru(dcbpy)2(NCS)2, known as the N3 dye, and the amphiphilic ruthenium(II) dye Z907. A reversible couple at E1/2=0.725 V vs. saturated calomel electrode (SCE) with a separation of 0.08 V between the anodic and cathodic peaks, was observed due to the RuII/III couple by cyclic voltammetry. Furthermore, this amphiphilic ruthenium complex was successfully used as sensitizers for dye‐sensitized solar cells with the efficiency of 3.72% at the 100 mW·cm?2 irradiance of air mass 1.5 simulated sunlight without optimization of TiO2 films and the electrolyte. |
