摘要: 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。

Abstract: This study integrates fundamental organic chemistry concepts, including the Knoevenagel condensation reaction, with cutting-edge research in organic solar cells. Through a laboratory experiment, students synthesized a wide-bandgap fused-ring electron acceptor material, A831. Analysis of the experimental data demonstrated that diminishing the electron-withdrawing ability of the terminal groups elevated the material’s lowest unoccupied molecular orbital (LUMO) energy level, thereby enhancing the voltage output of the organic solar cells. This experiment cultivates students’ ability to apply foundational knowledge to solve research problems, embodying the educational philosophy of “fundamental knowledge – practical application”. It is particularly suitable as a comprehensive course for senior undergraduate students.
