将本科课程中的脑文格反应等有机化学内容与有机太阳能电池研究前沿紧密结合，通过实验让学生深入了解有机化学课程中的化学反应。该实验利用脑文格反应合成了一个宽带隙的稠环电子受体材料A831，通过对实验数据进行分析，确定材料是通过削弱端基的拉电子能力，提升了材料的最低未占有分子轨道(LUMO)能级，进而获得高电压的有机太阳能电池。该实验充分培养了学生运用基础知识解决科研问题的能力，体现了“基础知识–实际应用”的有机实验教学模式，适合作为面向高年级本科生的综合实验教学课程。

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.
