A photoinduced electron transfer (PET)-based chemosensor possessing dual PET processes by simultaneously introducing both nitrogen and sulfur donors was achieved. The fluorescence signal of the free is in a normal-off state due to donor being insensitive environmental pH stimuli. As result, device can be used over wide span 3–11. Upon binding Al3+, significant enhancement with turn-on ratio 110-fold triggered inhibition from fluorophore.
Abstract Here, the photophysics and performance of single‐layer light emitting cells (LECs) based on a series ionic cyclometalated Ir(III) complexes formulae $\left[ {{\rm Ir}\left( ppy}} \right)_{\rm 2} \left( bpy}} \right)} \right]^ + {\rm PF}_{\rm 6}^ -$ phen}} where ppy, bpy, phen are 2‐phenylpyridine, substituted bipyridine phenanthroline ligands, respectively, reported. Substitution at NˆN ligand has little effect metal‐ligand to charge‐transfer (MLLCT) states functionalization this...
A highly sensitive and selective fluorescent chemosensor SC1 for Ag(+) based on a coumarin-Se(2)N chelating conjugate has been synthesized characterized. Due to inhibiting photoinduced electron transfer (PET) quenching pathway, enhancement factor of 4-fold is observed under the binding cation with detection limit down 10(-8) M range.
A probe based on the phenothiazine–acridine orange conjugate (Ptz–AO) has been designed and synthesized for sensitive selective detection of HOCl.
Cysteine (Cys) is one of the most important essential biothiols in lysosomes. Highly selective probes for specific detection and imaging lysosomal Cys over other biological thiols are rare. Herein, we developed a lysosome-targeted near-infrared fluorescent probe SHCy-C based on novel NIR-emitting thioxanthene-indolium dye. Due to turn-on fluorescence response elicited by intramolecular charge transfer (ICT) processes before after reaction with Cys, exhibits high selectivity sensitivity (16...
A fluorescent chemosensor with high sensitivity and selectivity for palladium species based on a conjugate of phosphine rhodamine B has been developed. The showed an excellent detection limit down to the 10−9 M range, which is lower than WHO content in drug chemicals.
We report the synthesis, characterisation, photophysical and electrochemical properties of a series cationic cyclometallated Ir(III) complexes general formula [Ir(ppy)(2)(phen)]PF(6) (ppy=2-phenylpyridine, phen=a substituted phenanthroline). A feature these is that phen ligands are with one or two 9,9-dihexylfluorenyl substituents to provide extended pi conjugation, for example, 3-[2-(9,9-dihexylfluorenyl)]phenanthroline 3,8-bis[2-(9,9-dihexylfluorenyl)]phenanthroline afford 6 9,...
A NIR rhodamine fluorophore, <bold>TJ730,</bold> with a large Stokes shift over 110 nm has been developed. Using the dye as platform, we have prepared two novel probes for detection of Cu<sup>2+</sup> well cytoplasmic and lysosomal imaging in living cells.
The surfaces of both 317L SS and EC were designed using lithography technology inductively coupled plasma etching, respectively.
A new C(3v)-symmetrical calix[6]azacryptand, that is, calix[6]tmpa (11), was synthesized by efficient [1+1] macrocyclization reactions. Remarkably, both linear and convergent synthetic strategies were applied lead to equally good overall yields. Calix[6]tmpa behaves as a single proton sponge appeared reluctant undergo polyprotonation, unlike classical tris(2-pyridylmethyl)amine (tmpa) derivatives. It also acts host for ammonium ions. Interestingly, it strongly binds sodium ion neutral guest...
A novel fluorometric sensing strategy based on the anion-induced rotation-displaced H-aggregates of styrylindolium dyes was employed to enhance selectivity fluorescent chemosensors for HSO4− detection. The marvelous H-aggregate opens new routes simple synthesis receptors tetrahedral anionic species.
A bifluorophore-based ratiometric fluorescent probe has been developed. The is cell-permeable and can be used as a FRET-based for lysosomal Cu<sup>2+</sup>imaging in living cells.
1-(9-Anthracenylmethyl)-3-ethylimidazolium iodide was heated in CH2Cl2 solution with silver oxide to afford a stair polymer of N-heterocyclic carbene silver(I), which gave strong anthracene-type fluorescence. The moiety could be displaced from this by pyridine known similar shape but tighter framework; showed an emission band at 579 nm arising Ag−Ag interaction.
The synthesis and photophysical properties are described for a series of porphyrin, phthalocyanine pyrazinoporphyrazine derivatives which bear four or eight peripheral fluorenyl substituents as antennae.

A novel water soluble Hg2+-selective chemosensor 1 with hemicyanine as fluorescent reporting group and NO2Se2 chelating unit ion binding site was reported. Chemosensor shows a specific Hg2+ selectivity discrimination between chemically similar ions in conjunction visible colorimetric change from red to colorless, potentially leading both "naked-eye" fluorometric detection of cations.
A novel strategy to design a fluorescent chemosensor for OCl− which can be used over pH span of 6–11 by integrating the reactive phenylhydrazo group within rhodamine 6G has been achieved. Upon reaction with OCl−, significant fluorescence enhancement was triggered detection limit down 10−9 M range.
