| 摘 要： | 合成了一种新的C，N-配位型环金属化钌染料敏化剂Ru-1，通过核磁共振氢谱以及红外光谱对该配合物进行了表征．由紫外-可见吸收光谱表明：该配合物的金属到配体的电荷转移跃迁（MLCT）吸收最大可达546nm，比传统的明星染料N3（Ru（dcbpy）2（NCS）2]，dcbpy=2，2＇-二联吡啶-4，4’-二羧酸）红移约10nm，且摩尔消光系数提高了约1．5倍．由此说明该配合物在长波方向表现出比N3更为优良的吸收性能，这对提高染料敏化纳米晶太阳能电池的光电转化效率十分有利．

| Abstract: | A new C, N-coordinated cyclometalated ruthenium sensitizer Ru-1 was synthesized and characterized by ＇HNMR and FT-IR spectra. The UV-Vis spectra Showed that the MLCT （metal to ligand charge transfer transition） absorptions of Ru-1 was centered at 546 nm. Compared with N3 （ Ru（dcbpy） 2 （NCS）2 ], dcbpy = 2,2＇- dipyridyl-4,4＇- dicarboxylic acid） , it is red-shifted 10 nm with its molar extinction coefficients increased about 1.5 times. These data showed that the absorptions of Ru-1 in the red region is better than that of N3, which is favorable to enhance the photoelectric conversion efficiency. |
