A Fluorescent Sensor for Dinitrobenzoic Acid Based on a Cyanuric Acid and Xanthene Skeleton
A new fluorescent sensor based on a dimethylxanthene skeleton has beensynthesized. Because of its oxyanion hole structure, this receptor includes a suitablecavity for the association of carboxylic acids. The receptor's fluorescence is quenchedupon addition of dinitrobenzoic acid.
متن کاملCrystal Growth, Optical and Thermal Studies of 4-Nitroaniline 4- Aminobenzoic Acid: A Fluorescent Material
The organic single crystals of 4-nitroaniline 4aminobenzoic acid (4NAABA) were grown from ethanol solvent. The grown crystals have been confirmed from single crystal XRD analysis. The UV absorption was carried out which shows the cutoff wavelength around 459 nm. The optical band gap of the crystal has been evaluated from the absorption spectra and absorption coefficient by extrapolation techniq...
متن کاملMechanism of inactivation of myeloperoxidase by 4-aminobenzoic acid hydrazide.
Hypochlorous acid is the most powerful oxidant generated by neutrophils and is likely to contribute to the damage mediated by these inflammatory cells. The haem enzyme myeloperoxidase catalyses its production from hydrogen peroxide and chloride. 4-Aminobenzoic acid hydrazide (ABAH) is a potent inhibitor of hypochlorous acid production. In this investigation we show that, in the presence of hydr...
متن کاملProbing Ternary Complex Equilibria of Crown Ether Ligands by Time-Resolved Fluorescence Spectroscopy
Ternary complex formation with solvent molecules and other adventitious ligands may compromise the performance of metal-ion-selective fluorescent probes. As Ca(II) can accommodate more than 6 donors in the first coordination sphere, commonly used crown ether ligands are prone to ternary complex formation with this cation. The steric strain imposed by auxiliary ligands, however, may result in an...
