Rhodamine thiospirolactone. Highly selective and sensitive reversible sensing of Hg(II)

Chem Commun (Camb). 2008 Apr 28:(16):1859-61. doi: 10.1039/b719473k. Epub 2008 Mar 10.

Abstract

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.
