A REUSABLE END-CAPPED BIPYRIDINE COMPOUND USEFUL FOR SELECTIVE DETECTION OF CYANIDE ANIONS AND PROCESS FOR PREPARATION THEREOF

摘要

The present invention describes the development of a end-capped bipyridine compound having formula (A) and the zinc complex having formula (B). The, assay having formula (1) can be used to estimate and quantify the amount of zinc ions by monitoring the fluorescence changes. The assay with formula (1) can be use to image and detect Zn2 ions in MCF7 cell lines. The zinc complex of formula (2) and (4) can be used as a fluorescent sensor for cyanide anions using analyte replacement protocol. The assay with formula (2) is, selective only to cyanide anions even in the presence of other competing anions. The assay with formula (3) having bright green solid state emission is used for the preparation of formula (4). The orange fluorescent powder of assay with formula (4) is used for the selective detection of CN ions in aqueous solution.
