Synthesis, cytotoxicity and bioimaging of a novel Hg²⁺ selective fluorogenic chemosensor

Abstract

A rhodamine B derivative <bold>2</bold> with terminal mercapto thiadiazole moiety was successfully synthesized and applied for selective recognition of Hg²⁺ in aqueous–acetonitrile (1 : 1, v/v, pH 7) solution by employing its photophysical properties.
