“…Herein, we report on a strategy to develop a redox-responsive luminescent lanthanide metallogel with a facile oxidation process based on 3,5-dinitrosalicylic acid (DNSA), europium (Eu 3+ ), and titanium dioxide (TiO 2 ) and thus denoted as DNSA/Eu 3+ /TiO 2 gel. DNSA possesses two functional groups (−COOH and −OH), which can form stable metallocyclic rings with metal ions after deprotonation, , thus DNSA can act as an energy-matched ligand for lanthanide ions. Moreover, for the redox reversibility of DNSA, the DNSA/Eu 3+ /TiO 2 gel exhibits a reversible luminescence “on–off” effect and color change in response to redox stimuli.…”

The development of reversible redox supramolecular gels capable of concurrent luminescence switch and visible color change with the facile redox process has always been an intriguing challenge. A redox-responsive supramolecular lanthanide metallogel with strong luminescence and yellow color is obtained via coordination interaction between 3,5-dinitrosalicylic acid (DNSA) and europium (Eu3+). Upon the addition of TiO2 to the prepared gel (DNSA/Eu3+ gel), the oxidation process of the gel (DNSA/Eu3+/TiO2 gel) can be easily achieved by UV irradiation. The DNSA/Eu3+/TiO2 gel exhibits a concurrent reversible “on–off” luminescence and color change in response to redox stimuli. The DNSA/Eu3+/TiO2 gel shows a concurrent quench of luminescence and a color change from yellow to red when the gel was stimulated by the reductant. Upon UV irradiation, the luminescence and color of the reduced DNSA/Eu3+/TiO2 gel restored to its initial state due to the strong oxidation ability of hydroxyl radicals derived from photocatalytic oxidation of TiO2. The results of UV–vis and mass spectroscopy indicated that the reversible redox responsiveness of DNSA/Eu3+/TiO2 gel depends on the reversible oxidation–reduction reactions of DNSA. Moreover, DNSA/Eu3+/TiO2 gel remains stable because the morphology of the gel had no change during the redox process. Exemplarily, the application of DNSA/Eu3+/TiO2 gels to achieve luminescent patterning was investigated. The results demonstrated that the prepared metallogel has potential applications in the fields of writable materials, anticounterfeiting, sensors, and others.

“…The 3,5-dinitrosalicylic acid lost both of its protons and behaves as a bridging ligand between two Mn atoms. This connection mode of salicylic acid or its derivatives between metal centers is one of the interesting connection modes in the MOFs [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Compound (1) is the first example with a one-dimensional helical chain structure compared to other clusters [ [26] and Bi 3 Ti 3 (sal) 8 -(Hsal) 2 [28] with this connection mode.…”

In (1), Mn atom exhibits five coordination while in the similar Co polymer the hexa coordination was found [30]. Maybe this is the reason of helical structure of (1) and simple polymeric structure of its Co analog.…”

IR, Raman and surface enhanced Raman scattering (SERS) spectra of 3,5-dinitrosalicylic acid (DNSA) were recorded and analysed. The vibrational wavenumbers were computed by the ab initio method using RHF/6-21G * basis and they were found to be in good agreement with the experimental values. The effect of the concentration dependence on the SERS intensity of the molecule was studied. The molecular plane assumes a tilted orientation with respect to the silver surface.
