چکیده
We report the synthesis, X-ray crystal structures and photophysics of new donor-acceptor oligomers of fluorene (F) and dibenzothiophene-S,S-dioxide (S) with constrained dihedral angles in the backbone. The materials display bright deep-blue fluorescence and evidence is presented for a planarised intramolecular charge-transfer (PICT) state in the F-S systems.

Photophysical Responses of Benzimidazolic and Benzoxazolic HydroxyCoumarin Dyes
We synthesized four novel benzoxazolic and benzimidazolic derivatives of 6-hydroxycoumarin and their photophysical properties were studied. The products with brilliant yellow color shades declared green fluorescence. The emission peaks of the products appeared 456–474 nm. The important characteristic for fluorescent compounds, the Stokes shift νA-νF, oscillator strength f, and fluorescence quan...

The novel fluorescentheterocyclic bidentate ligands have been synthesized by the high yields reaction of 8-(4-chlorophenyl)-3-Iso-butyl-3H-imidazo[4',5':3,4]benzo[1,2-c]isoxazol-5-amine with p-hydroxybenzaldehyde and p-chlorobenzaldehyde. The ligands reacted with Zn(II) ion to gained novel complexes. The optical properties of these structures were checked and the outcomes represented that t...
متن کاملModern fluorescent proteins: from chromophore formation to novel intracellular applications.
The diverse biochemical and photophysical properties of fluorescent proteins (FPs) have enabled the generation of a growing palette of colors, providing unique opportunities for their use in a variety of modern biology applications. Modulation of these FP characteristics is achieved through diversity in both the structure of the chromophore as well as the contacts between the chromophore and th...
متن کاملSynthesis, Spectral Characterization and DFT Calculations of New Co(II) Complexes Derived from Benzimidazoles
The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...
