Synthesis,Structures And Properties Of Sulfonate Complexes

In this paper,10 new compounds have been synthesized under room temperature or through hydrothermal synthesis method,by using the primary ligand disodium salt of 1.5-naphthalene dicarboxylic acid and second ligands including ethylene diamine,1.10-phenanthroline,phthalic diammonium and 4.4-bipyridine.Wherein the 5 compounds synthesized with ethylenediamine have the same structure.The crystal structures of the skeletons were determined by X-ray single crystal diffraction and SHELXTL-97.Chemical and physical properties were measured by X-ray powder diffraction?XRD?,infrared spectroscopy?IR?and thermal gravimetric analysis?TGA?The molecular recognition properties of the compounds have been studied by Fluorescence spectra of the suspension of compounds 1-10 in different small molecules solvents.Optical and electrical.properties of the surface of the compound 1-10 were studied by surface photovoltage and field induced surface photovoltage technique.Formula of the 10 complex compounds are as following:?1?-?5?[M?en??H₂O?₄]·1·5-nds?H₂O?₂M=Ni?1?,Co?2?,Cd?3?,Zn?4?,Cu?5??6?[Cd?H₂NC₆H₄NH₂?₄]·nds?7?[Ni?H₂NC₆H₄NH₂?₂?H₂O?2]·2nds·H₂O?8?[Fe(C₁₀N₂H₈)₂?nds?]n?9?[Pb(C₁₀N₂H₈)₂?nds?]H₂O CH₃CN?10?[Cu?bipy?₂?H₂O?₂]· nds-DMF H₂OThe compounds 1-5 were synthesized with ethylenediamine as the second ligand;the compound 6 and 7,with 1.10-phenylene diammonium as the second ligand;compounds 8 and 9,with 1.10-phenanthroline as the second ligand;compound 10,with 4.4-bipyridine as the second ligand.Wherein the compound 1-5 and 10 are 3D supramolecular coordination polymers;compound 6 and 7 are 0D coordination polymers with 0D clusters;compound 8 and 9 belong to 1D supramolecular structure.The fluorescent properties of compounds 1-10 suspensions in different small molecules solvents demonstrated that in a certain extent the compounds 1-10 have some recognition abilities for small molecule solvents.The compound 3 wherein methanol and acetone having an identification effect,The compound 8 cyclohexanone and butanol have to recognize the role of applied research in certain small molecule recognition.The results of the surface of the photovoltaic properties showed the photovoltaic response of compound 1,4,5,8 and 10 decrease with the increasing applied voltage,which means they have the nature of n-type semiconductor.While the photovoltaic response of compounds 2,3,6,7 and 9 increase with the enhancement of applied voltage,which means they have the nature of p-type semiconductor.
