“…31,32 However, the anion viz., acetate triggered Zn 2+ sensing by Salen type Schiff base are rarely reported. 33,34 Herein, we introduce a Schiff base fluorescent sensor [2,2′-((1E,1′E)-hydrazine-1,2 diylidenebis(methanylylidene))bis(4-bromo phenol)], H 2 L for Zn 2+ , derived from bromo-salicylaldehyde moiety which nearly covers all these requirements for Zn 2+ over coexisting metal cations in a DMSO-water medium via a ''turn on'' signaling response assisted by only OAcŕ with ∼ 54 times emission intensity increment. Our as-synthesized chemosensor H 2 L is the example of chemosensor for simultaneous detection of Zn 2+ and OAcŕ ions in a co-operative fashion.…”

Counter anion-triggered metal ion detection has been rarely reported by fluorimetric method. To address this challenging issue, a fluorescent probe (H 2 L) has been synthesized from bromo-salicylaldehyde and hydrazine hydrate, and structurally characterized by single crystal X-ray diffraction. The probe shows very weak fluorescence itself.However, its emission intensity increases in the presence of Zn 2+ over other metal ions. Surprisingly, the emission profile of this probe in presence of Zn 2+ is augmented only when acetate anion (OAcŕ) is present as counter anion, that allows for precise quantitative analysis by spectroscopic studies. The compositions and complexation among the probe, Zn 2+ ion, and OAcŕ are supported by ESI-MS, 1 H-NMR, and Job's plot. Based on these studies, it is confirmed that the binding ratio between probe: metal is 1:2 and the detection limit (LOD) for the Zn 2+ is 2.18 μM. The probe is capable of recognizing Zn 2+ ion in the wide range of pH∼6.5-9.5, and it could be efficiently recycled by EDTA. Furthermore, the combinatorial molecular logic gate and memory device have been constructed from the fluorescent behavior of H 2 L with Zn 2+ , OAcŕ, and EDTA input as based on NOT and AND gates. Interestingly, the aggregation-induced emission (AIEE) phenomenon is also perceived with greater than 50% water content in organic water mixtures, which are then useful for the detection of picric acid often used as explosive.

“…Although many reports are available regarding the individual detection of different types of metal ions or anions, the specific binding of metal acetates and fluorides is rarely reported. Recently, H. J. Zo et al (Song et al, 2013) reported the selective sensing of Zn (OAc) 2 using a bipyridyl-modified acetylene dye.…”

Here, we present a new bipyridyl moiety linked Schiff base (bipy-1) that is well characterized using spectroscopic techniques. Colorimetric and UV-vis titrations were used to study the photophysical properties of bipy-1 in the presence of various tetrabutyl ammonium salt of anions and metal salts containing different counter cations. bipy-1 showed selective recognition of dimethyl sulphoxide solution of tetrabutyl ammonium salt of F(-) ion accompanied with a UV-vis band at 529 nm and interesting binding of aqueous Co, Ni, and Cu acetates/fluorides, as confirmed by distinct color changes from fluorescent green to pink or orange and a strong band around 480-510 nm in the UV-vis spectrum. However, in the presence of Co, Ni, and Cu countercations, any form of metal acetate/fluorides was found to be able to respond to similar color changes from fluorescent green to pink or orange, showing a band around 480-510 nm. This type of output clearly indicates that the in situ formation of Co, Ni, and Cu acetates/fluorides also coordinates with bipyridyl nitrogen atoms.

Several naphthalene-based aldazine derivatives were developed as efficient colorimetric and fluorescence probes for selective ratiometric recognition of traces of zinc acetate. The derivative structures were characterized by single-crystal X-ray diffraction. The probes were used for in vitro tracking of zinc acetate in endophytic bacteria within rice root tissue and to image zinc acetate in human breast cancer cells (MCF7) by normal and fluorescence microscopy. Density functional theoretical studies were in close agreement with the experimental findings.
