Abstract

A novel selective fluorescent chemosensor has been synthesized with a phenanthrene-fused dipyrromethene structure. Selective binding of Cu(2+) by results in a complex that displays high selectivity and sensitivity for H2S. The signal transduction occurs via reversible formation-separation of the complex and CuS. Its potential utility for biological applications was confirmed by fluorescence imaging of H2S in live cells.
