含硫基超分子配位化合物的设计、组装与性能的研究的中期报告 Abstract: Asanimportantclassofsupramolecularcompounds,sulfur-basedsupramolecularcoordinationcompoundshavebeenwidelystudiedduetotheiruniquestructuralandelectronicproperties.Inthisreport,weprovideamid-termupdateonourresearchprojectfocusingonthedesign,assembly,andpropertiesofsulfur-basedsupramolecularcoordinationcompounds. Introduction: Thestudyofsupramolecularchemistryhasgreatlyexpandedourunderstandingofmolecularrecognition,self-assembly,andfunctionalpropertiesofmaterials.Sulfur-basedsupramolecularcoordinationcompounds,inparticular,haveattractedconsiderableinterestduetotheirpotentialapplicationsincatalysis,sensing,andoptoelectronics.Inourresearchproject,weaimtodesignandsynthesizenovelsulfur-basedsupramolecularcoordinationcompoundswithdiversestructuresandproperties. Designandsynthesis: Wehavedesignedandsynthesizedaseriesofsulfur-basedligandswithdifferentfunctionalgroups,suchasamine,pyridine,andimine,aswellasdifferentlengthsofalkylchains.Theseligandswerecharacterizedbyvarioustechniquessuchas1HNMR,13CNMR,andIRspectroscopy.Wehavealsopreparedarangeofmetalionsforcomplexation,includingCu(II),Zn(II),andNi(II). Assemblyandcharacterization: Thesynthesizedsulfur-basedligandswereusedtoformsupramolecularcoordinationcompoundswiththemetalions.TheassemblyofthesecompoundswasinvestigatedusingarangeoftechniquessuchasUV-Visspectroscopy,fluorescencespectroscopy,andX-raydiffraction.Wehavefoundthatthestructuresoftheresultingcoordinationcompoundsarehighlydependentonthenatureofthemetalion,thefunctionalgroupsontheligand,andthesolventused. Properties: Wehavealsoinvestigatedthepropertiesofthesulfur-basedsupramolecularcoordinationcompounds.Forinstance,wehavestudiedtheircatalyticactivityinvariousreactions,suchastheoxidationofalcoholsandthereductionofnitrocompounds.Wehavealsoexaminedtheiranti-bacterialactivityagainstdifferentstrainsofbacteria.Furthermore,wehaveinvestigatedtheirphotophysicalproperties,suchasfluorescenceandphosphorescence,whichsuggestpotentialapplications
