rhodamine-like dye. In the presence of Zn(II), this compound was found to exhibit highly enantioselective fluorescence enhancement at λemi > 730 nm and λexc = 690 nm when treated with 14 common aminoacids in aqueoussolution. An enantioselective fluorescence enhancement ratio up to 163 was observed. The mechanism of the fluorescence response of this probe was investigated by various spectroscopic methods.

fluorescent probes (A, B, C and D) have been synthesized, characterized, and evaluated for detection of lysosomal pHinsidelivingcells. The fluorescent probes display highly sensitive and selective fluorescent response to acidic pH as the acidic pH results in drastic structural changes from spirocyclic (non-fluorescent) forms to ring-opening (fluorescent) forms of the fluorescent probes. The fluorescence
The present disclosure relates to compounds of Formula I, II, or III and compositions of the same, which are reversible off-on or ratiometric fluorescent iron sensors and are useful in live-cell imaging of labile iron ions and their quantification in subcellular compartments, as well as treatment of diseases associated with iron dyshomoestasis.
