A real-time colorimetric and ratiometric fluorescent probe based on modulating the intramolecular charge transfer (ICT) of the coumarin platform for selective detection of sulfite is presented. This reaction based probe utilized the Michael addition to the dicyano-vinyl group with the detection limit of 5.8 × 10(-5) M. The probe displayed a high selectivity(More)
A coumarin TCF-based water-soluble near-infrared fluorescent probe was presented, which could be used for the rapid, colorimetric and ratiometric detection of SO2 derivatives with a detection limit of 0.27 nM. Moreover, this probe could successfully image the analyte in living cells.
Pyridinium functioned 7-hydroxy coumarin was presented as the first mitochondria-targeted ratiometric fluorescent probe CP for real time monitoring pH in living cells. Compared with commercially available mitochondrial trackers, CP possesses high specificity to mitochondria in living cells as well as good biocompatibility. Meanwhile, CP displays excellent(More)
A ratiometric fluorescent probe for SO2 derivatives based on the conjugate of carbazole and indolium was presented, which could selectively respond to HSO3(-) over other thiol compounds. More importantly, CZ-Id is a novel mitochondria-targeted ratiometric fluorescent probe to image exogenous SO2 derivatives.
A selenium-contained fluorescent ‘turn-on’ probe D-HMSe was developed for monitoring hydrogen peroxide. The probe D-HMSe is highly selective to hydrogen peroxide over other reactive oxygen species (ROS). An aggregation-induced enhancement (AIE) phenomenon was involved in the sensing process.
Due to the lack of a proper imaging approach, a veracious pH map of normal and abnormal cell is still rare. In this work, we presented a rhodamine-salicylaldehyde combination (Rh-SA2) as a novel pH probe, which has dual sensitive units for both acidic and basic environment. This dual sensitive probe acts like a chameleon in living cells and offers the(More)
Aedes albopictus is a primary nuisance pest and disease vector in China. Control of Ae. albopictus using current methods is difficult because of diverse larval breeding sites. In the present study, lambda-cyhalothrin was applied as a barrier spray to vegetation surrounding human dwellings for control of adult mosquito populations. Compared to the landing(More)
A multifunctional fluorescent sensor based on a cyclen-appended BINOL derivative (R-1) was synthesized and characterized. It can display on-off-type fluorescence change with high selectivity toward Cu(II) among 19 metal ions in 100% aqueous solution. Furthermore, the in situ generated R-1-Cu(II) ensemble could recover the quenched fluorescence upon the(More)
