Multiple target chemosensor: a fluorescent sensor for Zn(ii) and Al(iii) and a chromogenic sensor for Fe(ii) and Fe(iii)

Abstract

A multifunctional fluorescent and colorimetric chemosensor 1, based on two julolidine moieties as a binding and signaling unit, has been synthesized in a one-step procedure. Receptor 1 showed prompt responses toward Zn2+ and Al3+ ions through selective fluorescence enhancement in dimethylformamide (DMF), while the presence of 5% water made 1 detect only Zn2+. Moreover, with 1 the “naked eye” could sense iron by a clear color change. Upon the addition of Fe2+ and Fe3+ into each solution of 1, the color of the solutions changed from pale yellow to dark green for both Fe2+ and Fe3+. The binding modes of the complexes were determined to be a 1 : 1 complexation stoichiometry from a Job plot, 1H NMR titration and ESI-mass spectrometry analysis.
