油纸伞是中国具有千年历史的传统手工艺品，也是中国传统文化的重要象征。本文以一位老工匠为即将出嫁的女儿制作油纸伞作为嫁妆的故事为背景，深入探讨油纸伞制作过程中蕴含的化学原理，包括碱法制浆、柿漆粘结、朱砂附着和桐油防水等关键工艺。同时，本文挖掘其背后的思政元素，将文化、化学与思政教育有机结合，实现知识传授与价值引领的统一。

以五水合硫酸铜(CuSO₄·5H₂O)和4，4′-联吡啶(4，4′-bipy)为原料，通过室温固相合成法制备了纳米级铜配位聚合物{[Cu(4，4′-bipy)(H₂O)₃(SO₄)]·2H₂O}_n (Cu-CP)。扫描电镜结果显示，该材料呈现均匀颗粒状，尺寸分布在100~300 nm范围内。将其作为吸附剂用于吸附水溶液中的有机染料时，该材料对刚果红(CR)染料具有优异的吸附性能，吸附容量高达5 486 mg·g^-1，去除率达99.50%。吸附动力学和热力学研究表明，该吸附过程符合准二级动力学模型，且为单层化学吸附。此外，采用的球磨辅助室温固相合成策略具有操作简便、无需溶剂、易于放大及产率高等优势。

We used pentacarboxylic acid ligand 3, 5-di(2', 4'-dicarboxylphenyl) benzoic acid (H₅L) to synthesize two structural similarity lanthanide-cobalt heteronuclear bimetallic organic frameworks (Ln-Co-MOFs) by hydrothermal method: (C₂H₆NH₂)₅{[Eu₉Co(L)₆(H₂O)₅(OH)₄] ·5DMF}_n (1), (C₂H₆NH₂)₂{[Sm₉Co(L)₆(H₂O)₃Cl] ·5DMF}_n (2). The structures were characterized and the property was tested by single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetry, infrared, fluorescence spectra, and magnetism. The results show that 1 and 2 both belong to the trigonal R3 space group and have novel 3D structures and good thermal stability. Among them, 1 has strong fluorescence properties, which can sensitively identify drug molecules sulfasalazine and organic molecules glutaraldehyde. The detection limits could reach 0.95 and 2.10 μmol·L^-1, respectively. In addition, 1 and 2 were antiferromagnetic at 1 kOe.
