摘　　要：以9,10-二(氯甲基)蒽和吡啶胺硫醇为原料,设计合成了一种新型含吡啶硫杂六齿蒽基配体,并通过红外光谱、核磁共振、质谱、元素分析等技术进行了结构表征。研究了配体的紫外吸收和荧光发射性能,并探究了其与系列金属离子,如Ag^(+)、Co^(2+)、Cu^(2+)、Hg^(2+)、Pb^(2+)的相关作用。荧光光谱研究表明,这些金属离子与配体间都能够产生络合作用并促使配体的荧光猝灭,在等当量时以Cu^(2+)的作用最为显著。与其他离子不同的是,增大铅离子的浓度能够获得独特的荧光增敏作用。因此,该配体有望成为检测识别铅离子的荧光试剂。A nitrogen/sulfur-contained hexadentate anthracene fluorophore ligand with a pyridyl functional group,was prepared by reacting of 9,10-bis(chloromethyl)anthracene with 2-((pyridin-2-ylmethyl)amino)-ethane-1-thiol,and structurally characterized by means of infrared spectroscopy,nuclear magnetic resonance,mass spectrometry,elemental analysis.Electron absorption and fluorescence emission properties of the ligand were studied,and its correlation with various metal ions,e.g.,Ag^(+),Co^(2+),Cu^(2+),Hg^(2+),Pb^(2+),was explored.Fluorescence spectroscopy revealed that all the metal ions resulted to fluorescence quenching of the ligands at the equal equivalent and the copper ion the best one.In particular,continuing inducing the lead ions should arise the fluorescence rather than quench it.Therefore the ligand would be a promising fluorescent chemosensor for lead ions screening and detecting.
