摘要
用~1H NMR和^(13)C NMR谱研究了新型电化学发光探针六氟磷酸二(4,4’-二甲基-2,2’-联吡啶)·(4,4’-二羧酸-2,2’-联吡啶)合钌(Ⅱ)的立体结构,通过~1H^(-1)H COSY、^(13)C^(-1)H HETCOR谱对其氢谱和碳谱中的各谱峰进行了归属,并给出了氢谱和碳谱峰的化学位移值.
The 1H and 13C NMR spectra are reported for Ru(4,4'-dimethyl-2, 2'-bipyridine)2 (2,2'-bipyridine-4,4'-dicarboxylic acid) (PF6)2 that can be used as a new electrochemiluminescent probe in immunoasssay and nucleic acid hybridization assay. Because of the effect of Ru atom on ligands and complex steric configuration, it is difficult to attribute spectra of the title molecular. By using 2D 1 H-1H COSY and 1 H-13C HETCOR method, the proton and 13C NMR spectra are assigned completely, which provides a satisfactory method to quantitative and qualitative analysis of the title moleculer in the further study.
