Abstract Fluorescentprobes have been widely employed in biological imaging and sensing. However, it is always a challenge to design probes with high sensitivity. In this work, based on rhodamine skeleton, we developed a general strategy to construct sensitivity-enhanced fluorescentprobe with the help of theoretical calculation for the first time. As a proof of concept, we synthesized a series of

Flow cytometric detection of mitochondrial H2S was achieved with propargylic esters of rhodamine B which selectively react with H2S via cationic rhodamine-moiety directed thiolysis of the propargylic esters to give nonfluorescent rhodamine thio-spirolactone.

Rhodamine thiospirolactone. Highly selective and sensitive reversible sensing of Hg(ii)
A novel rhodamine thiospirolactone chemosensor 1 was found to develop prominent absorbance and fluorescence enhancements in the presence of Hg2+ in aqueous solution and this was suggested to result from the thiospiro ring opening induced by Hg2+ binding.
