为了更深入地研究表面张力的经典实验，利用Origin软件，采用多种函数模型对表面张力与浓度曲线分别进行拟合，并对每种函数拟合的优缺点加以讨论。其中对数函数拟合数学准确性较高，同时兼具物理意义，更贴切实况。明确了表面张力与浓度拟合的经典实验中以对数函数模型最为适宜。

A new polyoxovanadate compound [Co(pIM)V₂O₆] (1) was hydrothermally synthesized, where pIM stands for 2-(2-pyridyl)imidazole. For its characterizations, an integration of X-ray single crystal diffraction, powder X-ray diffraction, Fourier transform infrared spectra, and elemental analysis was accomplished. The compound exhibited a 2D architecture composed of VO₄ tetrahedra and CoO₃N₂ square pyramids via both edge - and corner - sharing. Considering the excellent catalytic oxidation features of polyoxovanadate, compound 1 was used as an efficient heterogeneous catalyst for the epoxidation of olefins with H₂O₂ as an oxidant, and could be reused without consuming activity. Besides, the magnetic studies indicated the antiferromagnetic interactions in 1.

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.

以2，5-二氟苯甲酸(HDFBA)为第一配体，2，2'∶6'，2″-三联吡啶(terpy)、1, 10-菲咯啉(phen)为第二配体，成功合成4种稀土有机配合物闪烁体：[Tb(DFBA)₃(terpy)(H₂O)] (1)、[Eu(DFBA)₃(terpy)(H₂O)] (2)、[Tb(DFBA)₃(phen)] (3)、[Eu(DFBA)₃(phen)] (4)。这些稀土有机配合物闪烁体展现出优异的X射线剂量响应性、光稳定性以及高达(25 100±2 000) photons·MeV^-1的稳态X射线激发的相对光产额。通过调节配合物中Eu³⁺和Tb³⁺的物质的量之比，实现了从绿色到红色的多色发光。将它们以一定的比例掺入聚乙烯醇(PVA)基质中获得均匀闪烁体薄膜，实现了高分辨(11.2 lp·mm^-1) X射线成像。

A coordination polymer {[Cd(H₂dpa)(bpy)]·3H₂O}_n (Cd-CP) was designed and hydrothermal synthesized based on 4-(2, 4-dicarboxyphenoxy) phthalic acid (H₄dpa), 2, 2′-bipyridine (bpy) and Cd(NO₃)₂·4H₂O. The structure was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, and infrared spectroscopy. Cd-CP belongs to the monoclinic crystal system with the P2₁/c space group and performs in a 1D double-chain structure. The adjacent double chains further form a 3D supramolecular network structure through hydrogen bonding. Thermogravimetric analysis shows that Cd-CP has good thermal stability. Fluorescence analysis showed that Cd-CP had good choosing selectively and was sensitive to metal ions (Fe³⁺ and Zn²⁺), 2, 4, 6-trinitrophenylhydrazine (TRI), and pyrimethanil (Pth). Interestingly, when Cd-CP was used for fluorescence detection of metal ions, it was found to have a fluorescence quenching effect on Fe³⁺ but had an obvious enhancement effect on Zn²⁺. Therefore, we designed an "on-off-on" logic gate. In addition, the mechanism of fluorescence sensing has been deeply explored.
