  Abstract  
  Use of chemosensor in the selective and specific detection of Zinc is intensively studied in recent times because of its vast biochemical involvement. Zinc is a trace metal, useful in biological growth and integral part of about 300 metalloenzymes. Iminephenolato function serves as potent fluorogenic support to Zn2+ ion. A Schiff base, 8,8'-((1E,1'E)-(((5-methyl-1,3-phenylene)bis(methyelene))bis(azanylylidene))bis (methanylylidene))bis(7-hydroxy-4-methyl-2H-chromen-2-ene), is synthesized by the condensation of 1,3-phenylenedimethanamine with 7-hydroxy-4-methyl-2-oxo-2H-chromene-8-carbaldehyde and is used for turn-on Zn2+ identification and the limit of detection (LOD) is 0.34 µM.
