Two new heteroleptic ruthenium(II) photosensitizers that contains 2,2';6,2''-terpyridine with extended π-conjugation with donor groups, a 4,4'-dicarboxylic acid-2,2'-bipyridine anchoring ligand and a thiocyanate ligand have been designed, synthesized and fully characterized by CHN, mass spectrometry, UV-vis and fluorescence spectroscopies and cyclic voltammetry. The new sensitizers have either 3,5-di-tert-butyl phenyl (m-BL-5) or triphenylamine (m-BL-6) groups, where the molar extinction coefficient of both the sensitizers is higher than the analogous ruthenium dyes. Both the sensitizers were tested in dye-sensitized solar cells using two different redox electrolytes.
设计、合成并通过元素分析、质谱、紫外-可见光谱和荧光光谱以及循环伏安法对两个新型的含扩展π共轭供体的偕二吡啶钌（II）光致剂进行了全方面的表征，其包含 2,2';6,2''-三联吡啶和 4,4'-二羧酸-2,2'-联吡啶锚定配体及硫氰酸根配体。新型敏化剂分别具有 3,5-二叔丁基苯基（m-BL-5）或三苯胺（m-BL-6）基团，两个敏化剂的摩尔消光系数均高于类似的钌染料。使用两种不同的氧化还原电解质，在染料敏化太阳能电池中对两种敏化剂进行了测试。
