“…heterogeneous catalytic industry, optical sensing, magnetics, biomedicine, and so forth. [7][8][9][10][11] In recent years, luminescent MOFs have attracted more and more attentions of community of scholars resulting from their possible application as luminescent sensors with high selectivity and sensitivity, fast response, and easy recoverability. [12][13][14][15] Under this background, some MOFs were synthesized and structurally analyzed, which show luminescence sensing properties for the probe of Fe 3+ , CrO 4 2À , Cr 2 O 7 2À , CS 2 , nitroaromatic explosives with high selectivity and sensitivity.…”

A new Cd(II) compound, also known as [Cd 2 (L 2 ) 2 ] n Áx(solvent) (1 H 2 L = 5-(4-pyridyl)methoxylisophthalic acid), has been facilely manufactured via the hydrothermal self-assembly reaction of Cd(NO 3 )Á4H 2 O and H 2 L. Single-crystal X-ray diffraction analysis demonstrated that compound 1 displays a three-dimensional pillar-layered structure with the one-dimensional opened passageway filled by lattice water molecules. Investigations of luminescent properties indicated that compound 1 discharges strong blue luminescence at normal temperature, and the solvent-free samples of 1a can be served as a luminescent sensor for the probe of Fe 3+ ions in the aqueous solution with highly selective reactions and hypersensitivity. Moreover, the treatment activity of the compound on focal cerebral ischemia/reperfusion was evaluated, and the specific mechanism was explored at the same time. The western blotting assay was conducted to assess the expression levels of the AQP4 protein in the brain tissue around ischemia. Besides, the activation of the superoxide dismutase was evaluated using enzyme-linked immunosorbent assay by measuring the content of the maleic dialdehyde and superoxide dismutase in the cerebrospinal fluid. The Cell Counting Kit-8 was used to determine the inhibitory activity of the compound on HMEC-1 human microvascular endothelial cells.

“…The formation of effective conductive paths in the ECAs is the key to obtain high electrical conductivity. Several conductive fillers have been studied in ECAs; these include cobalt nanoparticles [20], zinc complexes [21,22], cadmium [23], metal oxide [24], and so on. However, there are some issues such as aggregation and poor interconnect between conductive fillers with polymer resin, which need to be solved.…”

MXene represents new kinds of two-dimensional material transition metal carbides and/or carbonitrides, which have attracted much attention in various applications including electrochemical storage devices, catalysts, and polymer composite. Here, we report a facile method to synthesize Ti3C2Tx MXene nanosheets and prepare a novel electrically conductive adhesive based on epoxy resin filled with Ti3C2Tx MXene nanosheets by solution blending. The structure, morphology, and performance of Ti3C2Tx MXene nanosheets and epoxy/Ti3C2Tx MXene nanosheets composite were investigated. The results show that Ti3C2Tx MXene possesses nanosheet structure. Ti3C2Tx MXene nanosheets were homogeneously dispersed in epoxy resin. Electrical conductivity and mechanical properties measurements reveal that the epoxy/Ti3C2Tx MXene nanosheet composite exhibited both good electrical conductivity (4.52 × 10−4 S/m) and favorable mechanical properties (tensile strength of 66.2 MPa and impact strength of 24.2 kJ/m2) when the content of Ti3C2Tx MXene nanosheets is 1.2 wt %. Thus, Ti3C2Tx MXene is a promising filler for electrically conductive adhesive with high electric conductivity and high mechanical performance.

“…Luminescent CPs (LCPs) and MOFs (LMOFs) are designed for sensing on the basis of their structural diversity, tailorable pore size and tuneable chemical and physical properties. For the development of LCPs and LMOFs, the introduction of either π‐electron rich aromatic moieties with some recognition site into the frameworks or metal ions (Zn 2+ , Cd 2+ or Ln 3+ ) or the combination of both can be used to detect the emission signal during sensing [2d,4–15] …”

Utilizing a bent bis(naphthalene) and hydroxy-based dicarboxylate linker (mbhna) and two different tridentate polypyridyl ligands (bpma and bpta), four new coordination polymers (CPs) of Zn(II) and Cd(II) namely, [Zn(mbhna 4), are reported. Based on their solidstate molecular structures determined by single-crystal X-ray diffractometry, all are found to be helical 1D CP; interestingly, 4 crystallizes in a chiral space group, showcasing the formation of a chiral CP from achiral components. For the presence of naphthalene moieties in mbhna, their excellent emissive nature is studied in different solvents and further utilized to selectively detect aromatic amines, particularly 4-nitroaniline in water with detection limits at the ppm level. Utilizing the Stern-Volmer plots, spectral overlap, and competitive test, their mechanism of action has been established. Furthermore, these are recyclable with good stability after sensing experiments.
