cyclotriveratrylene - Opis:
- A novel supramolecular fluorescent molecular probe constructed on cyclotriveratrylene based derivative allied to 8-quinolinesulfonyl chloride (8QSC) was synthesized and used for the detection of copper ions among the various cations. Using 1H-NMR, 13C-NMR, and ESI-MS techniques the compound was successfully characterised. Furthermore the complexation behaviour of 8QSC-CTV with different cations were studied. A shift in the absorption spectra showed the detection of copper ion with the ligand 8QSC-CTV which concludes the strong binding interaction between the ligand and the cation. Furthermore the metal ion showed quenching in the emission spectra. The quantum yield of the metal complex was also studied. The stern volmer analysis concluded that the mechanism of fluorescence quenching is either purely dynamic or purely static.
