合成了一种新型的配合物{[Cu(Phen)(Nap)_2]_2·(EtOH)_2·(H_2O)_2}(Phen=1,10-菲咯啉,Nap=1-萘甲酸,EtOH=乙醇)。通过元素分析、红外光谱、热重等测试技术对其进行了表征,同时用X射线单晶衍射确定了其晶体结构,其配合物为双核铜结构。利用循环伏安法和发射光谱研究了该配合物的电化学和发光性能;采用紫外光谱和荧光光谱法研究了配合物与小牛胸腺DNA(ct-DNA)的相互作用。结果表明,配合物为不可逆氧化还原过程,其荧光发射光谱为416 nm,与小牛胸腺DNA(ct-DNA)以沟面结合方式相互作用,配合物结合常数Kb1=4.68×10~3L/mol。
A new complex {[Cu (Phen) (Nap) _2] _2 · (EtOH) _2 · (H_2O) _2} (Phen = 1,10-phenanthroline, Nap = 1-naphthoic acid, EtOH = Ethanol). Its structure was characterized by elemental analysis, infrared spectroscopy and thermogravimetric analysis. The crystal structure was also confirmed by X-ray single crystal diffraction. The complex was a dual-core copper structure. The electrochemical and luminescent properties of the complexes were investigated by cyclic voltammetry and emission spectroscopy. The interaction between the complexes and calf thymus DNA (ct-DNA) was studied by UV and fluorescence spectroscopy. The results showed that the complex was an irreversible redox process with a fluorescence emission spectrum of 416 nm. The interaction of the complex with the calf thymus DNA (ct-DNA) was found to be groove-surface binding. The binding constant Kb1 was 4.68 × 10-3 L / mol .
