鉴于传统Fe(OH)₃胶体电泳实验存在胶体浪费、渗析耗时、缺乏探究性等局限，故做如下改进：1) 以Fe(OH)₃废液为原料，利用胶溶法将其再生，实现循环利用；2) 改进渗析工艺，提高胶体纯化效率；3) 引入AgI胶体探究环节，增强创新性与趣味性；4) 引入纸片电泳，科教融合，培养学以致用的意识。经反复验证，上述方案行之有效，并已在本校推广，教学反响热烈。

Under hydrothermal conditions, semi-rigid 4-(1-carboxyethoxy)benzoic acid (H₂cba) and Ni(Ⅱ) ions reacted with imidazole derivatives 1,4-di(1H-imidazol-1-yl)benzene (1,4-dib) and 4,4'-di(1H-imidazol-1-yl)-1,1'-biphenyl (4, 4' dib) to form complexes {[Ni(cba)(1, 4 dib)(H₂O)_0.5] ·0.5H₂O}n (HU21) and {[Ni(cba)(4, 4' dib)(H₂O)_0.5] · 0.5H 2O}n (HU22), respectively. Singlecrystal X-ray diffraction analysis revealed that both complexes HU21 and HU22 contain binuclear [Ni₂(CO₂)₂(H₂O)]²⁺ units, which are further bridged together via cba^2- anions to form 1D [Ni₂(H₂O)(cba)₂]_n chains in HU21 and HU22. In addition to the [Ni₂(H₂O)(cba)₂]_n chains, large right-handed and lefthanded helical chains were constructed by Ni(Ⅱ) ions, water molecules, and 1,4-dib ligands in HU21, with diameters of up to 1.6 nm along the b-axis. These helical chains are further joined together in a 1∶1 ratio to form a 3D framework. Subsequently, the [Ni₂(H₂O)(cba)₂]_n chains are incorporated into the 3D framework to build a six-connected dense network with a point symbol of (4⁴.6¹¹) in HU21. In complex HU22, left-and right-handed helical chains were also observed. However, unlike the 3D framework constructed by helical chains in HU21, these helical chains in HU22 can only form a 2D layer. Adjacent layers are packed together in an ABAB pattern to form a six-connected framework in the presence of [Ni₂(H₂O) (cba)₂]_n chains. UV-Vis absorption experiments indicated that complexes HU21 and HU22 are semiconductor materials with strong light absorption capacities in the ultraviolet and visible regions. Moreover, magnetic experiments showed that HU21 and HU22 exhibit similar antiferromagnetic behaviors.

Employing the reaction of chiral nitronyl nitroxide radical and rare-earth ions, two 2p-4f hetero-spin meso complexes [Ln(hfac)₃((R)-MePP-Ph-NIT)]₂, where Ln=Eu (1) and Dy (2), hfac=hexafluoroacetylacetone; (R)-MePP-Ph-NIT=2-(4-((R)-tert-butyl-2-methylpiperazine-1-carboxylate)phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, have been assembled. In both complexes, two chiral radicals ligate to two Ln(Ⅲ) ions to produce a cyclic dinuclear structure. Complex 1 shows the characteristic fluorescence emission of the Eu(Ⅲ) ion. In complex 2, the frequency-dependent out-of-phase susceptibility signals connected with magnetic relaxation confirm single-molecule magnet (SMM) behavior.

Based on the 5-(3, 4-dicarboxyphenoxy) isophthalic acid (H₄dppa) ligand, two lanthanide metal-organic frameworks (Ln-MOFs) were designed and synthesized by hydrothermal synthesis: {(dima)[Dy(dppa)(H₂O)₂]·2.5H₂O}_n (Dy - MOF) and {(dima) [Eu(dppa) (H₂O)₂]·1.5H₂O}_n (Eu - MOF) (dima=dimethylamine cation). The structures were characterized by elemental analysis, infrared spectroscopy, single-crystal X-ray diffraction, etc. Dy-MOF and Eu- MOF are hetero-isomorphic 2D network structures, and adjacent 2D networks further form 3D supramolecular network structures through hydrogen bonding. Fluorescence analysis shows that Dy-MOF and Eu-MOF have excellent fluorescence properties at room temperature, and Dy-MOF has excellent fluorescence sensing properties, which can efficiently and high-sensitively detect a variety of pollutants in water: aniline (ANI), nitrobenzene (NB), tetracycline (TC), pyrimethanil (PTH), and tryptophan (Trp). The fluorescence quenching mechanism of Dy-MOF in detecting pollutants was also investigated.

A new metal-organic framework (MOF) {[Cd(L)_0.5(4, 4'-bpy)_0.5]·H₂O}_n (1), where H₄L=(1, 1': 4', 1″-terphenyl)-2, 2″, 4, 4″-tetracarboxylic acid, 4, 4'-bpy=4, 4'-bipyridine, was synthesized by hydro-solvothermal method. The structure of complex 1 was characterized by single-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, thermogravimetric analysis, and infrared spectrum analysis. The analysis of single crystal structure shows that 1 is a 3D structure, belonging to the monoclinic crystal system, C2/c space group. Cd(Ⅱ) connects L^4- and 4, 4'-bpy to form a 2D plane structure, and the layers are connected by L^4- to form a 3D network structure. The MOF shows good stability and can be used for the detection of tetracycline (TET) and p-nitrophenol (4-NP) by fluorescence quenching. The detection limits of TET and 4-NP were 0.15 and 0.062 μmol·L^-1, respectively. In addition, the fluorescence quenching mechanism of 1 was also studied. 1 can be successfully applied to the determination of TET and 4-NP content in Yanhe water samples.

A unique 3D luminescent metal-organic framework, namely [Cd(L)(H₂O)_0.5]·DMF·2.5H₂O (1), where H₂L=3-(tetrazol-5-yl)triazole, has been successfully prepared and characterized. The framework has demonstrated excellent luminescence properties and structural stability in the water system. Notably, the luminescence intensity of 1 was significantly quenched by Cr(Ⅵ) (1 mL of Cr₂O₇^2- or 150 μL of CrO₄^2-, 1 mmol·L^-1), leading to the formation of an "on-off" luminescence silencing system (Cr₂O₇^2-@1), which was capable of accurately detecting Cr(Ⅵ) in the water system. The primary mechanism responsible for luminescence quenching was the Forster resonance energy transfer (FRET) process. Additionally, by removing the involvement of the FRET process, the luminescence intensity of the Cr₂O₇^2-@1 system could be restored, allowing for the highly selective and sensitive detection of ascorbic acid (AA) in water systems. Moreover, it has been demonstrated that 1 can successfully detect AA in vitamin C tablets, yielding recovery rates ranging from 98.20% to 103.33% and relative standard deviations (RSDs) ranging from 1.78% to 3.42%. Based on the findings of this experiment, a luminescent "IMPLICATION" molecular logic gate has been constructed utilizing AA and Cr(Ⅵ) as the chemical inputs, respectively.
