In this study, the bathocuproine (BCP) compound was used as a fluorescent chemosensor. The selectivity and sensitivity of BCP have been investigated against some metal ions of biological and environmental importance. The results obtained from the ultraviolet-visible region (UV-vis.) and the fluorescence spectroscopy experiments revealed that the BCP sensor showed selectivity and sensitivity only to Manganese (II) ions in the experimental conditions studied. In addition, the binding stoichiometry of BCP and Mn2+ was determined to be 1:1 by the Benesi-Hildebrand method. %K Fluorescent Chemosensor %K Mn< %K sup> %K 2+< %K /sup> %K Fluorescence Quenching %K Selectivity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=120434
