A new nanosheet fluorescent chemosensor (GO–NH–COUR) based on graphite oxide (GO) covalently functionalized with a 4-methyl-7-aminocoumarin (NH 2 -COUR) has been prepared. The GO were prepared by a modified Hummers method. The products were characterized by TEM, XRD, and FT-IR. The photophysical properties of GO, NH 2 –COUR and GO–NH–COUR in aqueous and ethanol solution have been investigated...
A highly selective fluorescent indicator for copper, substituted with an aminoquinoline group at the position 3 or 5 of the BODIPY has been synthesized. The indicator has very low fluorescence quantum yield in acetonitrile with emission maxima at 580 nm. Upon binding copper it shows 50 nm bathochromic shifts with a change of solution color and a large increase in the fluorescence intensity. The fluorescence...
