Long-Wavelength Fluorescent Chemosensors for Hg2+ based on Pyrene

Long-Wavelength, Reaction-Based, Fluorescent Sensors

Effect of substituents on FRET in rhodamine based chemosensors selective for Hg2+ ions.

The effect of substituents on FRET in two newly designed rhodamine-based Hg(2+) ion selective chemosensors (L¹ and L²) has been explored by a systematic experimental and theoretical study. Comparison of these sensors in the analytical study and imaging of Hg(2+) ions in living cells has also been included.

Fluorescent chemosensors based on conformational restriction of a biaryl fluorophore.

Fluorescent chemosensorssmolecules that change their fluorescence in response to substrate bindingsoffer an extremely sensitive optical method for the real-time monitoring of molecular interactions.1 Such chemosensors are finding increased use in fields as diverse as biology, medical analysis, and environmental monitoring.1a,6 The majority of fluorescent chemosensors operate by one of three mec...

Coumarin-Derived Fluorescent Chemosensors

Fluorescent chemosensors are highly valuable in a variety of fields including environmental chemistry, analytical chemistry, and bio-medicinal science. They have provided accurate, on-line, and low-cost detection of toxic heavy metal ions, anions, and enzymes with high selectivity and sensitivity. Coumarins, with the structure of benzopyrone, have many advantages including high fluorescence qua...

Fluoranthene based fluorescent chemosensors for detection of explosive nitroaromatics.

A novel fluoranthene based fluorescent chemosensor for the detection of picric acid (PA) at the parts per billion (ppb) level was evaluated. Static fluorescence quenching was the dominant process by intercalative π-π interaction between fluoranthene (S(1)) and nitroaromatics.
