A novel coumarin-based fluorogenic probe bearing the 2-picolyl unit (1) was developed as a fluorescent chemosensor with high selectivity and suitable affinity in biological systems toward Cu2+ over other cations tested. The fluorescence on−off mechanism studied by femtosecond time-resolved (TRF) upconversion technique ab initio calculations. receptor can be applied to monitoring of ion aqueous solution pH span 4−10. To confirm suitability 1 for applications, we also employed it detection...
[reaction: see text] N-(Rhodamine-6G)lactam-N'-phenylthiourea-ethylenediamine (1) was developed as a fluorescent and colorimetric chemodosimeter in aqueous solution with broad pH span (5 approximately 10) high selectivity toward Hg2+ but no significant response other competitive cations, such Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Pb2+, Cd2+, Ca2+, Mg2+, K+, Na+, etc. The Hg2+-promoted ring opening of spirolactam the rhodamine moiety induced cyclic guanylation thiourea moiety, which resulted dual...
A self-calibrating bipartite viscosity sensor 1 for cellular mitochondria, composed of coumarin and boron-dipyrromethene (BODIPY) with a rigid phenyl spacer mitochondria-targeting unit, was synthesized. The showed direct linear relationship between the fluorescence intensity ratio BODIPY to or lifetime media viscosity, which allowed us determine average mitochondrial in living HeLa cells as ca. 62 cP (cp). Upon treatment an ionophore, monensin, nystatin, observed increase 110 cP.
We report here a mitochondria-targetable pH-sensitive probe that allows for quantitative measurement of mitochondrial pH changes, as well the real-time monitoring pH-related physiological effects in live cells. This system consists piperazine-linked naphthalimide fluorescence off–on signaling unit, cationic triphenylphosphonium group targeting, and reactive benzyl chloride subunit fixation. It operates environment within whole cells displays desirable response to acidification. Moreover,...
