Synthesis Structure And Property Of Copper(Ⅰ) Complexe Containing The Ligand Of P^O And N^N

Copper(â… ) complexes have been attraction much attention by people and theresearch on them has been one of major fields on coordination chemistry because oftheir diversity of structures,novel photophysical and photochemical properties. Atpresent much more reaseaches on copper(â… ) complexes are focus on same nuclearcomplexes than the iso-nuclear complexes. Some ligands with the group of P^O N^Nand ferocence were used to synthesis a series of mono-and binuclear and isonuclearCopper(â… ) complexes in this dissertation.We find some interesting phenomena anddraw some conclusions.1. Two binuclear copper(â… ) complexes [Cu(μ2Cl)₂(PPh₃)₃](1) and [Cu(μ2Cl)₂-dppeo)₃] (dppeo=bis(diphenylphosphino) ethane monoxide) were prepared andcharacterized by single crystal X-ray diffractional analysis IR and elementalanalysis. Both complexes have strong photoluminescent properties with can beattributed to intra-ligand charge transfer.2. Two mononuclear copper(â… ) complexes[Cuâ… (phen)(dppeo)](3) [CuCl(phen)(dppeo)](4) were prepared and characterized by single crystal X-ray diffractionalanalysis IR and elemental analysis.Crystal structure analysis of Cu(â… ) reveale asrongly distorted tetrahedral configuration and the atom of oxygen in P=O is notincorporated with metal. The atom of oxygen can incorporated with rare earthion,which provides a method to synthsesis isonuclea Copper(â… ) complexe.3. A new substituted 2, 2'-bipyridine ligand was been synthesized through thematerial of ferrocence. With the new ligand, a isonuclear complexe of copper(â… ) andFe(â…¡) was synthesized. The low-energy absorption bands above 350nm are attributedto a MLCT transition The electrochemical studies of ligand and isonuclear complexereveal that the bulk group linked with ferrocence can stablize Fe(â…¡).
