“…In view of these characteristics, metal phosphonates may act as promising potential materials for multitudinous applications, such as proton conduction, [51–53] magnetic materials, [54–56] catalysis, [49,53] ion exchange, [51,57] gas sorption, [58] chemical sensing materials, [59–65] and so on. Interestingly, it is noted that molecular lanthanide phosphonate complexes (LnPs) and phosphonate based Ln‐MOFs (LnP‐MOFs) are rarely reported even though they possess essentialities of advantages as both Ln‐MOFs and metal phosphonates [66–69] . In addition, as the phosphonate ligands emit potential blue light emission, the luminescence properties of LnPs and LnP‐MOFs may be tuned due to the incorporation of metal‐ and ligand‐based luminescence [66–69] .…”

Molecular lanthanide phosphonates [Ln 2 (H 3 tpmm) 2 (H 2 O) 6 ] • xH 2 O (Ln=Eu, EuP; Ln=Tb, TbP) were synthesized. Single-crystal X-ray diffraction confirmed that EuP has a sandwich-like dinuclear structure, in which the Eu(III) center adopts a {EuO 8 } distorted dodecahedral geometry. XRPD patterns prove that TbP and EuP are isomorphous and isostructural.EuP and TbP are highly thermally stable approaching 450 °C and exhibit red-and green-light emissions from the characteristic 4 f-4 f transition of the Eu 3 + and Tb 3 + , respectively. Interestingly, luminescence modulation is achieved for the chemically mixed Eu/Tb phosphonate analogues, c-Eu x Tb 2-x P (x = 1.5, 1, 0.5), and physically mixed Eu/Tb phosphonate materials, p-yEuP : zTbP (y : z = 3 : 1, 1 : 1, 1 : 3), with varying the excitation wavelength. Of particular note, near-white-light emission is also achieved for c-EuTbP, p-EuP : TbP, and p-EuP : 3TbP when excited at 365 nm. Therefore, these dinuclear molecular lanthanide phosphonates emitting excitation wavelength and Eu 3 + : Tb 3 + ratio dependent luminescence might be potential candidates for color-tunable luminescence materials and white-light-emitting materials. On the other hand, the bright green-light emission makes TbP to be an excellent reusable luminescence sensor for selective detection of Fe 3 + with Stern-Volmer quenching constant (K SV ) of 9.66 × 10 3 M À 1 and detection limit (DL) of 0.42 μM through absorption competition caused luminescence quenching effect.

“…[21][22][23][24] In the past several years, our research group has been working on bifunctional anionic units as building blocks to construct new complexes with fascinating structures and intriguing properties. [25][26][27][28] At present, in the exploration of phosphonate complexes, some bifunctional or multifunctional ligands such as aminophosphonates or phosphonocarboxylates have been adopted due to their versatile coordination ability.

As the most attractive and fastest growing fluorescent sensing materials, metal-organic compounds have demonstrated great potential for the detection of various types of chemicals. Two fluorescent phosphonate complexes(2) with diverse structures were designed and synthesized for this purpose from ((2'-cyano-[1,1'-biphenyl]-4-yl) methyl)phosphonic acid (H 2 L) and copper ions with various valence state under solvothermal conditions. The structures of 1 and 2 are determined by single X-ray crystal diffraction, and further characterized by elemental analysis, IR, TGA and PXRD. The two complexes demonstrate diverse properties on sensing Fe 3 + ions, ketone and some antibiotics, and the according detection limits are obtained, indicating which could be applied as a fast, recyclable, and multi-responsive fluorescence sensor. The sensing activity diversity between 1 and 2 toward different analytes was also discussed based on the possible sensing mechanisms to further explore the possible factors affecting the sensibility of the materials.

In this work, a novel Mn(II) chain coordination polymer (Mn-CP), {[Mn(iip)(2bbpum) 0.5 (H 2 O) 3 ]•2H 2 O} n [H 2 iip = 5-iodoisophthalic acid, 2bbpum = N,N′-bis(2-pyridinemethyl)oxamide] was synthesized under ambient conditions. Mn-CP further assembles into a 3D supramolecular architecture through hydrogen bonds, halogen bonds, and ππ stacking interactions. The composite Mn-CP/nafion membrane has low activation energy for proton transfer, which results in its temperature-insensitive proton conductivity. The cyclic voltammetry demonstrates that the Mn-CP electrode (Mn-CP/GCE) shows quite different redox properties in 0.1 M H 2 SO 4 and 0.1 M PBS aqueous solutions. The Mn-CP/GCE exhibits a couple of irreversible redox peaks with an oxidation peak potential suitable for the nitrite oxidation in 0.1 M H 2 SO 4 . Quite differently, in the PBS aqueous buffer solution, the Mn-CP electrode has a couple of irreversible redox peaks. The reduction peak potential is appropriate for the H 2 O 2 reduction. So, the Mn-CP/GCE can be used not only in the electrocatalytic oxidation of NO 2 − but also in the electrocatalytic reduction of H 2 O 2 . The amperometric response reveals that the Mn-CP/GCE exhibits high-selective and extremely sensitive oxidation sensing of NO 2 − and reduction sensing of H 2 O 2 . The exponential detection range is 0.01−20 mM for NO 2 − and 0.01−10.5 mM for H 2 O 2 . The linear detection range for both H 2 O 2 and NO 2 − is 0.01−0.10 mM. The detection limit is 1.865 μM for NO 2 − and 8.57 μM for H 2 O 2 . The Mn-CP/GCE exhibits high electrochemical stability and fine reproducibility. Moreover, the strategy can be translated to a portable screen-printed electrode (SPE). The Mn-CP/SPE shows more sensitive sensing to NO 2 − and H 2 O 2 than Mn-CP/GCE. Moreover, it can detect NO 2 − and H 2 O 2 efficiently in the real-world samples. So, Mn-CP may be a potential dual nonenzymatic electrochemical sensory material for NO 2 − via oxidation sensing and H 2 O 2 via reduction sensing.
