| 摘要: 合成了2个新的含1，3，4-噁二唑官能团的联吡啶配体及其相应的钌(Ⅱ)配合物Ru(CPOD)(dcbpy)(NCS)2(Ru-1)和Ru(DPOD)(dcbpy)(NCS)2(Ru-2)(CPOD=4-羧基-4′-[2-(4-壬氧基苯基)-5-苯基-1，3，4-噁二唑]-2，2′-二联吡啶, DPOD =4，4′-二[2-(4-壬氧基苯基)-5-苯基-1，3，4-噁二唑]-2，2′-二联吡啶，dcbpy=4，4′-二羧基-2，2′-二联吡啶)，并通过红外光谱、循环伏安、紫外可见吸收光谱、元素分析和光电流-光电压曲线实验对其结构和光电转化性质进行了表征。这些配合物的最大MLCT态吸收位于555 nm，摩尔消光系数可达1.43×104 L·mol-1·cm-1。它们的光化学和电化学性质表明：激发态能级与TiO2导带底能级匹配，电子能够注入到TiO2导带中。将它们敏化到纳米晶TiO2电极上，光电转化效率为2.4%。 |

| Abstract: Two new amphiphilic ruthenium complexes with new bipyridyl ligands, Ru(CPOD)(dcbpy)(NCS)2(Ru-1) and Ru(DPOD)(dcbpy)(NCS)2(Ru-2)(CPOD=4-carboxy-4′-[2-(4-nonyloxyphenyl)-5-phenyl-oxadiazoyl]-2,2′-bipyridine, DPOD=4,4′-di[2-(4-nonyloxyphenyl)-5-phenyl-1,3,4-oxadiazoyl]-2,2′-bipyridine,dcbpy=4,4′-dicarboxy-2,2′-bipyridine), were synthesized and characterized by IR spectra, cyclic voltammetry, UV-Vis spectra, elemental analysis and I-V curves. They exhibit good MLCT absorptions and high molar extinction coefficients (~1.43×104 L·mol-1·cm-1 at 555 nm). The spectroscopic and electrochemical measurements show that the excited states of these complexes match the conduction band of titanium dioxide. They were used as sensitzers for dye-sensitized solar cells and their photoelectric conversion efficiencies are nearly 2.4%. |
