Synthesis and fluorescence properties of a boron-dipyrrin functionalized perylenediimide derivative

A dual-channel dendritic chemosensor for Hg²⁺ with high FRET efficiency was designed and synthesized.

A ratiometric lysosomal pH probe based on the coumarin–rhodamine FRET system

The ratiometric pH probe RC1 was constructed by integrating a coumarin moiety as a FRET donor into a rhodamine moiety as a FRET acceptor. The probe with a pK_a of 4.98 could detect pH in the range of 4.20–6.00 and selectively stain lysosomes.

A novel ratiometric pH probe for extreme acidity based on FRET and PET

The ratiometric pH probe RC1 was constructed by coumarin–rhodamine dyad. RC1 with a pK_a of 3.21 could be used for measuring pH in the range 2.20–4.20 with high selectivity and visualizing extremely acidic pH conditions in bacteria.

Rhodamine derived colorimetric and fluorescence mercury(ii) chemodosimeter for human breast cancer cell (MCF7) imaging

Condensation of rhodaminehydrazone with naphthalene-1-carboxaldehyde generates a colourless probe, RDHDNAP that can selectively detect Hg²⁺through generation of a pink color along with significant fluorescence enhancement.

One single molecule as a multifunctional fluorescent probe for ratiometric sensing of Fe3+, Cr3+ and colorimetric sensing of Cu2+

The reagent Rh-C, incorporating a rhodamine moiety and a coumarin backbone and prepared via click chemistry, was developed as the first single molecule for detecting Cu²⁺, Fe³⁺ and Cr³⁺. Its response to Cu²⁺ in different solutions is visible to the naked eye and it exhibits a ratiometric fluorescence response to Fe³⁺ in methanol and Cr³⁺ in acetonitrile.

A new rhodamine-derived fluorescent chemodosimeter for Cu2+in aqueous solution and its application in living cell imaging

A new rhodamine-derived fluorescent chemodosimeter for imaging of Cu²⁺in living cells was developed under a coordination-promoted hydrolysis mechanism.
