Abstract

A series of monostyryl boron dipyrromethenes appended with an NO ₄, NO ₂S ₂, N ₃O ₄, or N ₃O ₂S ₂-type ligand have been prepared and characterised. While the UV-Vis spectra of the former three compounds in CH ₃CN/H ₂O (2:3 v/v) do not respond towards a wide range of metal ions, the derivative with an N ₃O ₂S ₂-ligand exhibits a highly selective and sensitive spectral response towards Hg ²⁺ ions. The absorption band is blue-shifted by 40 nm due to inhibition of the intramolecular charge transfer process upon metal complexation. The fluorescence is also turned on giving a strong emission band at 572 nm. The colour changes can be easily detected by the naked eye. The results suggest that this compound serves as a promising colourimetric and fluorescent sensor for Hg ²⁺ ions in this mixed aqueous medium. © 2012 The Royal Society of Chemistry.
