“…The design and synthesis of highly selective chemosensors for metal ions, such as Cu 2+ , Fe 3+ , Zn 2+ ,Cd 2+ , Mn 2+ , Hg 2+ and Pb 2+ , have attracted a great deal of attention in the scientific community [1][2][3][4][5][6][7][8]. Among these important metal ions, the trivalent form of iron (Fe 3+ ) is the most essential trace elements in biological systems, and it plays an important role in many biochemical processes at the cellular level [9][10][11][12].…”

“…[16][17][18] In the case of one of the receptors, the fluorescent response for trivalent metal ions was proposed to relate to the ionic valence rather than to the kind of metal cations. 18 However, this is not the case in EW1.…”

A julolidine-containing naphthylamine probe (EW1) was prepared for sensing specific metal ions. Probe EW1 afforded a broad low fluorescence at 500-600 nm in acetonitrile, but gave a relatively stronger fluorescence at 540 nm in methanol. EW1 showed a selective turn-on emission for Cr 3+ , indicating the formation of a 1:1 complex of the probe EW1 and chromium ion. However, EW1 showed a selective turn-off response with Cu 2+ in CH 3 OH. The emission band of EW1 at 540 nm was quenched only with Cu 2+ and not with other control metal ions. The absorption band of EW1 at 410 nm progressively decreased, and a new absorption at 390 nm appeared upon progressive addition of Cu 2+ . All spectroscopic titration experiments and ESI mass data provided evidence for the formation of a 1:1 complex between EW1 and Cu 2+ .

“…Even though several fluorescent probes are available for the detection of divalent or trivalent ions, probes useful for the collective detection of trivalent metal ions are very few in number. In the last couple of years, few reports based on 4 the chemosensors for trivalent metal ion detection are published in various international journals [29][30][31][32][33][34]. Most of these fluorescent probes operate based on metal ion induced fluorescence 'turn-on' or 'turn-off' mechanisms.…”
