The influence of metal cations such as Mn 2+, Fe2+, Fe3+, Co2+, Ni 2+, Cu2+, Zn2+, Cd2+, Hg 2+, Pb2+ and Al3+ on the spectroscopic properties of the ligands was investigated in acetonitriledichloromethane (1:1) by means of absorption and emission spectrometry. Absorption spectra show isosbestic points in the spectrophotometric titration of Fe2+, Zn2+, Cu2+, Pb2+ and Hg2+. The results of spectrophotometric titration experiments disclosed the complexation compositions and complex stability constants of the novel ligands with Fe 2+, Zn2+, Cu2+, Pb2+ and Hg 2+ cations. The monoazatetrathia crown ether showed good sensitivity for Cu2+ with linearity in the range 5.0×10-72. 5×10-6 M and detection limit of 1.6×10-8 M. © 2010 Elsevier B.V.eninfo:eu-repo/semantics/closedAccess1-Bromomethyl-pyreneAzathia donor atomCrown etherCu2+ cationFluorescence spectroscopyStability constant1-Bromomethyl-pyreneAcetonitrile-dichloromethaneComplex stabilityCu²⁺ cationDetection limitsDonor atomsEmission spectrometryIsosbestic pointMacrocyclesMacrocyclic compoundsMetal cationNitrogen-SulfurNovel ligandsSensor systemsSpectrophotometric titrationsSpectroscopic propertyStability constantSulfur atomsAbsorptionAbsorption spectroscopyAtomsCrown ethersEthersFluorescenceFluorescence spectroscopyManganeseMercury (metal)Organic compoundsPositive ionsSpectrophotometersSpectrophotometrySulfurTitrationZincLigands1-Bromomethyl-pyreneAzathia donor atomCrown etherCu2+ cationFluorescence spectroscopyStability constant1-Bromomethyl-pyreneAcetonitrile-dichloromethaneComplex stabilityCu²⁺ cationDetection limitsDonor atomsEmission spectrometryIsosbestic pointMacrocyclesMacrocyclic compoundsMetal cationNitrogen-SulfurNovel ligandsSensor systemsSpectrophotometric titrationsSpectroscopic propertyStability constantSulfur atomsAbsorptionAbsorption spectroscopyAtomsCrown ethersEthersFluorescenceFluorescence spectroscopyManganeseMercury (metal)Organic compoundsPositive ionsSpectrophotometersSpectrophotometrySulfurTitrationZincLigandsArticle131480881410.1016/j.jlumin.2010.12.0082-s2.0-79952315067Q2WOS:000289326000045Q1
