Rhodamine thiospirolactone. Highly selective and sensitive reversible sensing of Hg(II).
A novel rhodamine thiospirolactone chemosensor was found to develop prominent absorbance and fluorescence enhancements in the presence of Hg(2+) in aqueous solution and this was suggested to result from the thiospiro ring opening induced by Hg(2+) binding.
