【摘要】 合成了两种新型开链冠醚及其稀土配合物[Eu（pic）₃La]（1）和[Eu（pic）₃Lb]·4H₂O（2）(La=N,N,N’,N’,-四苯基-2,3-萘-二（杂氧乙酰胺）,Lb=N,N,N’,N’,-四苯基-2,7-萘-二（杂氧乙酰胺）,并对其进行了结构表征。荧光光谱实验表明:配合物的荧光强度随溶剂配位能力增强而减弱。此外,通过光谱法研究了配合物与DNA的作用方式,结果表明:配合物与DNA均以插入方式键合,但配合物1与DNA的作用强于配合物2。更多还原

【Abstract】 Tow novel open-chain crown ethers and its rare earth complexes[Eu（pic）₃L^a]（1）, [Eu（pic）₃L^b]·4H₂O（2）（L^a=N,N,N’,N’-tetraphenyl -2,3-naphthyl-bis（oxaacetamide）,L^b=N,N,N’,N’-tetrap -henyl-2,7-naphthyl-bis（oxaacetamide） ）were synthesized and characterized.The fluorescence spectra showed that the complexes were reduced with the raising coordination ability of solvent.In addition,the interaction between the complexes and DNA was studied by means of spectrometry.The results showed that the complexes could bind to DNA by intercalative mode,while the complex 1 interacting with DNA was stronger that the complex 2.更多还原
