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...
متن کاملCoumarin-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...
متن کاملFluorescent signaling based on control of excited state dynamics. Biarylacetylene fluorescent chemosensors.
We have previously reported that metal ion binding could restrict the excited state rotation of a biaryl chromophore, suppressing intersystem crossing and leading to increased emission. We have now applied the restriction of excited state dynamics to suppression of the other fundamental nonradiative decay pathway, internal conversion, in biarylacetylenes. This indicates that both nonradiative d...
متن کاملFemtogram detection of explosive nitroaromatics: fluoranthene-based fluorescent chemosensors.
Herein we report a novel fluoranthene-based fluorescent fluorophore 7,10-bis(4-bromophenyl)-8,9-bis[4-(hexyloxy)phenyl]fluoranthene (S(3)) and its remarkable properties in applications of explosive detection. The sensitivity towards the detection of nitroaromatics (NACs) was evaluated through fluorescence quenching in solution, vapor, and contact mode approaches. The contact mode approach using...
متن کاملFluoranthene 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.
