以甲基苯并15-冠-5(MB15-C-5)和Na2[M(SCN)4](M=Pd,Pt)为原料,合成了冠醚配合物:[Na(MB15-C-5)(H2O)]2[Pd(SCN)4]1和[Na(MB15-C-5)(H2O)]2[Pt(SCN)4]2.通过元素分析、红外光谱、核磁共振氢谱、差热-热重(TG-DTA)等测试方法对其结构进行表征.研究了配合物1与小牛胸腺DNA(CT-DNA)的作用,结果表明配合物1与DNA具有较强的相互作用.
Two methyl-benzo-15-crown-5 (MB15-C-5) complexes: [Na(MB15-C-5)(H2O)]2[Pd(SCN)4] (1)和[Na(MB15-C-5) (H2O)]2 [Pt(SCN)4](2)have been synthesized by methyl-benzo-15-crown-5 with Naz VM (SCN)4](M = Pd,Pt). The complexes were characterized by elemental analysis, IR, 1H NMR spectra and TG-DTA. The DNA-binding properties of complex (1) with calf thymus DNA (CT-DNA) have also been investigated by fluorescent spectra. The results show that complex (1) have strong interactions with CT-DNA.
