Ni(II)/Yb(III)-metallogels for distinctive fluorescent ‘turn-on’ detection of m-phenylenediamine: Toward construction of multiple logic gates
New versatile Schiff base gelator (HL) and its highly selective Ni(II)-and Yb(III)-based metallogels 1–2 have been synthesized and characterized by spectral techniques. Gelator HL in presence of triethylamine (Et3N) with Ni(NO3)2·6H2O and anhydrous Yb(NO3)3 in DMF/MeOH(1:1) solvents forms MG1 and MG2 supramolecular gels, respectively at room temperature (rt). Rheological results show thermal stability up to 100 ℃ and structurally rigid nature of MG1 and MG2. Remarkably, MG1 and MG2 were examined for identification of cations, anions, nitroaromatics and aromatic amines (AAs) but unable to recognize any analytes except for m-phenylenediamine (MPD) by using MG1. Metallogel MG1 shows highly selective response to MPD environmental pollutant with a limit of detection (LoD) of 7.58 × 10-7 M, without any interference of competing analytes. Interestingly, depending upon fascinating fluorescent On-Off-On switching behavior, molecular logic device has been fabricated with AND and IMPLICATION-logic gates function by employing the chemical inputs (i) HB, Ni(II) (MG1), Yb(III) (MG2) and (ii) HB, MG1 and MPD based on emission change at different wavelengths as output signal.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
