A multi-controllable selective fluorescent turn-on chemosensor for Al3+ and Zn2+ based on a new diarylethene with a 3-(4-methylphenyl)-1H-pyrazol-5-amine Schiff base group

We synthesized a new fluorescent probe 1O by attaching a diarylethene molecule to a functional group. The probe can be used to detect Al 3+ and Zn 2+ at the same time with high selectivity, and its detection limit is very low. When Al 3+ was added, the fluorescence intensity was increased 310 folds, and was accompanied by a fluorescent color change from black to grass-green. Similarly, after the addition of Zn 2+ , the fluorescence intensity was enhanced 110 folds, with a concomitant color change from black to yellowgreen. Moreover, based on the properties of 1O, we designed a logic circuit, and that also can be used for water sample testing.

“…In comparison to other metal ions, few examples of dual responsive fluorescent probes for Al 3+ and Zn 2+ have been described to date. [28][29][30][31] In general, probes that rely on fluorescence emission at different wavelengths perform much better than those that rely only on fluorescence emission at a single wavelength, which may be achieved by modifying the media. On the other hand, to detect various analytes or ions, several strategies (such as metal ion complexes, excimer formation, and conjugated polyelectrolytes) have been utilized.…”

A tripodal pentadentate mono‐imine derivative, 2‐({2‐[bis‐(2‐amino‐ethyl)‐amino]‐ethylimino}‐methyl)‐phenol (L2) is employed for ‘turn on’ fluorescence recognition of Zn2+ and Al3+ at two different wavelengths. Chelation‐enhanced fluorescence (CHEF) assisted inhibition of excited‐state intramolecular proton transfer (ESIPT) is proposed as the sensing mechanism. The 1HNMR, mass, IR spectral data, Jobs experiment and single crystal X‐ray structure of the [Ni(II)‐L2] complex (N1) strongly support the structure of L2 and its interaction with Zn2+ and Al3+. Density functional theoretical (DFT) studies indicate higher stability of the Zn2+ and Al3+ adducts over free L2. The recognition of Zn2+ and Al3+ at two different emission wavelengths allows to construct a binary logic gate. Moreover, L2 is useful for determination unknown concentration of Al3+ in real water samples. The complex N1 catalyses the catechol oxidation reaction.
