| 摘要: 以多联吡啶类配体取代咪唑3-鄄位，合成了2个配体，进而得到了2个钌配合物[Ru（tpy-PhCH2-Im-Naph）2]（PF6）4（C1）和[Ru（2，2'-bpy）2（2，2'-bpy-（CH2-Im-CH3）2）]（PF6）4（C2）（tpy=2，2'：6'，2"-三联吡啶，bpy=2，2'-联吡啶，Im=咪唑，Naph=5，7-二甲基-1，8-萘啶），通过核磁、质谱、元素分析，紫外、荧光等对这些化合物进行了表征，经X-射线晶体衍射分析确定了配合物C1的晶体结构。结构解析表明：配合物C1是离子型化合物，沿c轴方向堆积成规律的孔洞状。电化学性质测试揭示了氧化还原是一个单电子可逆的过程，对应的可逆对为Ru（Ⅲ）/Ru（Ⅱ），E1/2分别为1.26和1.32 V。C1和C2与CO2的加合物的红外光谱测试表明，这些化合物在碱的作用下能形成碳卡宾，可与CO2结合。 | ||||||||||

| Abstract: Ruthenium(Ru(Ⅲ)Ru(Ⅱ)) complexs with polypyridine-based derivative ligands, [Ru(tpy-PhCH2-Im-naph)2](PF6)4 (C1) and [Ru(2,2'-bpy)2(2,2'-bpy-(CH2-Im)2)](PF6)4(C2) (tpy=2,2':6',2"-terpyridine, 2,2'-bpy=2,2'-bipyridine, Im=imidazole, Naph=5,7-dimethyl-1,8-naphthyridine) have been synthesized, and were characterized by 1H NMR, ESI-MS, UV-Vis, fluorescence spectra, elemental analysis. Single-crystal X-ray diffraction analysis reveals that C1 is a cation-anion complex, and constructed of molecular stacking along the c axis to form cavities structure. Cyclic voltammetry studies on the complexes showed one electron Ru(Ⅲ)/Ru(Ⅱ) reversible couple with E1/2 of 1.26 V and 1.32 V, respectively. In addition, the CO2 adducts of C1 and C2 were investigated by IR spectra. CCDC: 957798, C1. | ||||||||||
