摘要
用１ＨＮＭＲ法研究了钯（Ⅱ）－ＮＴＰ－Ａ体系内金属离子与配体以及配体与配体之间的相互作用．其中ＮＴＰ代表腺苷５′－三磷酸（ＡＴＰ）和尿苷５′－三磷酸（ＵＴＰ）；Ａ代表１，１０－邻菲口罗啉，２，２′－联吡啶和Ｌ－色氨酸．实验发现，三元配合物体系中ＡＴＰ的Ｈ－Ｃ（２），Ｈ－Ｃ（８）和Ｈ－Ｃ（１′）与ＵＴＰ的Ｈ－Ｃ（５），Ｈ－Ｃ（６）和Ｈ－Ｃ（１′）都发生明显高场位移．此外。
The intramolecular aromaticring stacking interactions in ternary mixedligand palladium(Ⅱ)nucleotide (NTP)aromatic heterocyclic ring base(A) have been studied by 1HNMR, Where NTP refers to adenosine 5′triphosphate (ATP) and uridine 5′triphosphate (UTP); A refers to 1, 10phenanthroline, 2,2′bipyridyl, and Ltryptophane. The experiment reveals that Chemical Shifts of HC(2) and HC(8) and HC(1′) of ATP, and HC(5) and HC(6) and HC(1′) of UTP in corresponding ternary complexes were upfield shifted. Influence of the electron transfer and coordination environment on stability of ternary mixedligand complexes is also discussed.
