The invention describes the development of end-capped bipyridine compound and the zinc complex. The assay can be used to estimate and quantify the amount of zinc ions by monitoring the fluorescence changes. The assay can be used to image and detect Zn2+ ions in MCF7 cell lines. The zinc complex can be used as a fluorescent sensor for cyanide anions using analyte replacement protocol. The assay is selective only to cyanide anions even in the presence of other competing anions. The assay having bright green solid state emission is used for the preparation. The orange fluorescent powder of assay is used for the selective detection of CN- ions in aqueous solution.
