Synthesis and Characterization of Some Coumarin Fluorescent Dyes
The synthesis of some fluorescent coumarin dyes derived from coumarin-3-carboxylic acid were described.The new dyes are obtained by condensation of coumarin – 3 carboxylic acid derivatives with para substituted ortho phenylenediamines and cyclisation of the mono condensed ortho phenylenediamines in an acid medium. The obtained dyes were characterized from their physico-chemical point of view by...
متن کاملNIR-fluorescent coumarin-fused BODIPY dyes with large Stokes shifts.
A series of novel non-symmetrical coumarin-fused BODIPY dyes were synthesised. Their absorption and emission properties are strongly influenced by substitution in the coumarin moiety. Diethylamino-substituted dyes showed near-IR emission with large Stokes shifts (up to 144 nm) and good fluorescence quantum yields.

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...
متن کاملHyperspectral Imaging of Fluorescent Dyes
Resonon utilizes line-scan spectral imaging, where a scene is limited to one dimension with a slit, and then imaged off a diffraction grating to obtain spectral information for each pixel along the slit. A second spatial dimension is obtained by scanning the object as multiple frames are collected. Here, electrophoresis was used as the scanning mechanism, as illustrated in Figures 1 and 2. Prot...
