Synthesis,Structures And Properties Of New Macrocyclic Metalloligands And Complexes

Chiral coordination polymers have showed their broad application prospects in optical materials, molecular recognition, new sensors, magnetic materials and heterogeneous catalysis. And coordination polymers that contain phenanthroline moiety have a wide range of applications in the field of life sciences, as well as the catalytic, new photoelectric material, material testing and other scientific research fields. Thus, they have attracted a lot of attention of research.?1? The synthetic method of macrocylic oxmide mononuclear complex NiL¹ was improved and a new metalloligand NiL² was synthesized. They were characterized by IR spectra and UV-vis spectra.?2? Macrocyclic metalloligand NiL¹ was used to react with metal ions and cyclohexanediamine or?1S, 2S?-diphenylethylenediamine, for the preparation of chiral coordination polymers. Although no desired results were achieved, three new complexes {[Cd?NiL¹??H₂O?₂]·2DMF}n?1?, {[Mn?NiL¹??CH3OH??H2O?2]·CH3OH·0.5H2 O }n?2? and the complex?3? from NiL¹, Cu?NO3?2?3H2O and?1S, 2S?-diphenylethylenediamine were obtained. Their structures were determined by X-ray single crystal diffraction.?3? The reaction of the metalloligand NiL² with Zn?ClO4?2·2H2O, gave a new complex?4?. Its structure was also determined by X- ray single crystal diffraction.?4? Two 2D coordination polymers {Cd?NiL¹??phen?}n?5? and {Zn?NiL¹??phen?}n?6? were prepared. Their structures were determined by X-ray single crystal diffraction.?5? Compounds 1, 2, 5 were also characterized by IR spectra, UV-Vis spectra, TG and XRD. Compound 5 was also characterized by fluorescence spectrum.
