A novel coumarin derivatives based fluorescent chemosensor CBH was designed and synthesized by Schiff base reaction, which was connected by 7-(N,N-diethylamino) coumarin-3-aldehyde and 3-methyl-2-benzothiazolinone hydrazone through C=N. X-ray single crystal structure analysis indicated that two aromatic groups of the CBH were almost in the same plane. It displayed enhancement of the fluorescent intensity and absorbance when the sensor CBH interacted with Hg2+ ions. The chemosensor CBH exhibited a good sensitive and selective recognition towards Hg2+ ions in the presence of other important relevant metal ions.
