Synthesis And Application Research Of Diphenylphosphinate Amidinate Or Metal Compounds

The functional material research is one of the active field in chemistry and material.It is an essential way to synthisize some novel functional materials based on the characteristic of supramolecular compounds.In recent years,this has promoted the research into the synthesis and characterization of ionic organic supramolecular and coordination polymers.The series characteristic catalysts,nanometer materials,electric and magnetic materials had been synthesized.In this paper,we designed and synthisized a series of hydrogen bond assisted electrostatic supramolecular polymers and coordination polymers.Further, their optical and magnetic properties were studied.By the addition and oxidation reactions ofα-hydrogen-free nitriles with various amide lithium,ten novel compounds were prepared and characterized.The fluorescence and magnetic properties were determined. The detailed contents are divided into four sections:Partâ… :A briefing on the latest theoretical and applied progress of supramolecular chemistry was given.Especially the development of the synthises and properties on ionic supramolecular polymers and coordination polymers.Partâ…¡:The reaction of LiN(SiMe₃)₂ with 1,4-dicyanobenzene in the ratio of 1:1 or 1:2 were carried out,followed the metatheses of chlorodiphenylphosphine and oxidizing by hydrogen peroxide,two compounds,[C₆H₄(1,4-C(NH₂)(=NPPh₂))₂]L₁ and[4-CN-C₆H₄-C(NH₂)₂] [Ph₂PO₂]L₂ were prepared.With the similar reaction of dimethylamide lithium or diethylamide lithium with cyanobenzene,1,4-,1,3-, 1,2-dicyanobenzene or tolunitriles,total of five compounds,3,4,5,6 and 8,were prepared.The molecular structures of these compounds were determined by single crystal X-ray diffraction.The solid and solution fluorescence properties of compounds 3,6,8 were measured.Partâ…¢:In the reactions of compounds L₁,L₂ with the transition metal and the main group metals salts,the anion of L₂ was replaced by chloride of copper chloride dihydrate or nitrate of hexahydrate zinc nitrate.Two novel supramolecular ionic polymers 9 and 10 were formed. Under hydrothermal conditions,the compound 11 was synthesized by L₁ and the cobalt chloride,it is an amorphous fibrous coordination polymer. According to the analysis results of compound 11,the ligand is diphenylphosphinate anion L₃.Then we used diphenylphosphinate sodium to replace L₁ and obtained the compound 11 too.It is noted that this is the first amorphous fibrous coordination polymer based on our knowledgement.Samely,the amorphous fibrous diphenylphosphinate zinc(â…¡) and lanthanum(â…¢) coordination polymer were synthesized.The magnetic measurement revealed that the magnetic property of amorphous fibrous diphenylphosphinate cobalt(â…¡) is as same as that of the crystalline.Partâ…£:The contents of Chapter 1-3 were summarized.The rule in the process of synthesis for diphenylphosphinate organic or metallic compounds was submitted.The application of these compounds in optical and the magnetic materials was viewed.
