A mitochondria-targetable probe Mito-DHP for nitric oxide (NO) was designed and synthesized by introducing dihydropyridine and triphenylphosphonium (TPP) moieties into boron dipyrromethene (BODIPY) dye. Mito-DHP was able to effectively detect nitric oxide through the aromatization of dihydropyridine to fluorescent pyridine product under oxygen-free conditions. The probe Mito-DHP showed high selectivity...
A new type of copper nanoclusters was synthesized by a one-pot reaction using cysteamine as a capping agent and reducing agent (Cys-CuNCs). The synthesized CuNCs exhibited a spherical shape and a monodisperse and strong fluorescent emission characteristic peak at 430nm when exciting at 330nm. The Cys-CuNCs were demonstrated as a fluorescent chemodosimeter for the selective detection of Al3+. In the...
p-Nitrophenol (p-NP) contaminants seriously endanger environmental and living beings health, hence to establish a sensitive and selective method is of great importance for the determination of p-NP. In this work, boron and nitrogen co-doped carbon dots (B,N-CDs) were synthesized by one-step hydrothermal method using 3-aminophenylboronic acid as the sole precursor. The product was characterized through...
A novel rhodamine based sensor RBH was developed and synthesized by rhodamine B with 3-methyl-2-benzothiazolinone hydrazone, which exhibited high selectivity and sensitivity for sensing Cu2+ ions in the presence of other important relevant metal ions in aqueous acetonitrile. As an “off-on” fluorescent sensor, RBH exhibited a UV–vis absorption increase at 570 nm and a 132-fold significant fluorescence...
A new colorimetric and fluorescent chemosensor for visual determination of carbonate ions was developed by the microwave assisted solvent free synthesis of 7,8-dihydroxy-3-(4-methylphenyl) coumarin (DHMC). The structural characterization of DHMC was confirmed by microanalysis and spectroscopy methods (MALDI-TOF, FT-IR, 1H NMR, 13C NMR, and 2D HETCOR). The binding behaviors of DHMC were investigated...
A new highly selective fluorescent chemosensor for formaldehyde (FA) has been synthesized based on boron dipyrromethene as fluorophore and o-phenylenediamine (OPDA) as reaction group. When FA is added, the fluorescence emission band of the chemosensor red shift (from 525 nm to 548 nm) accompanied by an increase in intensity with strong green fluorescence was observed. This chemosensor also exhibited...
