Opis

Here we report the synthesis and Characterization of Vanillin and Cinnamaldehyde- rhodamine based signalling systems selective recognition of Fe(III) and Cu(II) ions. The Vanillin and Cinnamaldehyde molecule was used as a recognition moiety and rhodamine-6G and rhodamine B was used as a signalling moiety. The excellent fluorescent response to Fe(III) and Cu(II) in ACN/water (1:1, v/v) can be detected even by the naked eye, which provides a facile method for the visual detection of Fe(III) and Cu(II). Complexation of the Fe(III) and Cu(II) ion opens the spirolactum ring of rhodamine moieties to produce specific colour change as well as fluorescence enhancement.
