Peptide-appended pillar[n]arene (n = 5, 6) derivatives have been synthesized. 1H NMR and IR studies revealed that the molecules adopt a tubular conformation in solution lipid bilayer membranes. Kinetic measurements using fluorescent labeling method with vesicles these can efficiently mediate transport of amino acids across membranes at very low channel-to-lipid ratio (EC50 0.002 mol %). In several cases, chiral selectivity for acid enantiomers was achieved, which is one key functions natural...
For the first time, a new near-IR "turn-on" fluorescent chemosensor with high selectivity for Hg(2+) ions was designed according to twisted intramolecular charge transfer (TICT) mechanism. The selective fluorescence enhancement effect can be optimized by modulating solvent systems. And this naphthalenedimide-based sensor long wavelength absorption and emission used image intracellular in living Hela cells.
To develop sensitive and selective S2– chemosensors, a new disubstituted polyacetylene (P2) bearing pyridine moieties in the side chains was prepared conveniently through postfunctional method, strong green fluorescence of which could be completely quenched by Cu2+ ions at concentration as low 2.0 × 10–6 mol/L diluted solutions. Based on displacement strategy, utilizing much higher stability constant complex Cu2+, solution P2 recover upon addition trace anions, with detection limit down to...
Highly luminescent and stable CdSe quantum dots (QDs) modified with 4-substituted pyridine type ligands containing thiourea groups: 1-(4-fluorobenzoyl)-3-(5-(pyridin-4-yl)-1,3,4-thiadiazol-2-yl)thiourea (PyTU); were prepared through a ligand exchange process, characterized by transmission electron microscopy (TEM), fluorescence spectroscopy, UV-vis spectroscopy FT-IR spectroscopy. The synthesized nanocomposites show higher (FL) intensity are more in comparison original QDs. PyTU–CdSe QDs...
Novel β-cyclodextrin–4,4′-dipyridine supramolecular inclusion complex-modified silver nanoparticles were synthesized for the colorimetric determination of Yb3+ ions in aqueous solution with high sensitivity (the visual detection limit was 2 × 10−7 M), viaYb3+-induced aggregation to form chain-like aggregates.
A novel colorimetric and fluorescent sensor for Pd2+ has been developed based on the Pd-catalyzed deallylation. The displays a highly sensitive selective response with significant changes in both color (from orange to blue) fluorescence (quenching).
Three shape-persistent aromatic hydrazide macrocycles that bear phenylalanine tripeptide chains have been synthesized. These can insert into lipid bilayers to form single-molecular ion channels which exhibit a high NH4(+)/K(+) selectivity.

Based on analysis variable‐temperature 1 H NMR...
Abstract A novel colorimetric chemosensor PBIOSi has been designed and synthesized. The addition of F − to a THF solution resulted in an obvious color change (from red green) short time because the specific cleavage SiO bond by . It was interesting that showed excellent selectivity for detection over other halides. UV‐Vis absorption fluorescence were changed linearly with concentration range 0–10 µmol/L.
Pyrazoline and its derivatives often exhibit strong emissions in dilute solutions, but their emission intensity is dramatically reduced the solid state due to intermolecular interactions between neighboring molecules. In this report, we successfully synthesized a new pyrazoline 4-(3-(4-(decyloxy)phenyl)-1-(2,3,5,6-tetrafluoro-4-(trifluoromethyl)phenyl)-4,5-dihydro-1H-pyrazol-5-yl)-N,N-diethylaniline (PPDPD), into which seven fluorine (F) atoms were incorporated. state, PPDPD emits blue light...
