笔者在大学入学之初就受教于华彤文老师，后来跟随华老师做研究、搞教学、写教材，直至担任《大学化学》主编时依然听取华老师的教诲。在此文中分享40余年来近距离观察、感受和学习华老师严谨治学、勇于担当的教学与研究的态度和方法，期待我国的化学教育教学事业薪火相传，持续发展。

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。

The hydrated tricyclohexyltin theophylline-7-acetic acid (tpH) complex [Sn(C₆H₁₁)₃(tp)(H₂O)] was synthesized via an ethanol solvothermal method using tricyclohexyltin hydroxide and tpH in a 1∶1 molar ratio. The complex was characterized by IR, ¹H (¹³C) NMR, elemental analysis, and powder X-ray diffraction, and the crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the orthorhombic system with space group Iba2, and the central tin atom is in a five-coordinated trigonal bipyramidal configuration. Quantum chemistry ab initio calculations were performed to investigate the stability, molecular orbital energy, and frontier molecular orbital characteristics of the complex. Additionally, its thermal stability, electrochemical properties, and in vitro anticancer activity were evaluated.

Under solvothermal conditions, 1, 4-naphthalenedicarboxylic acid (H₂ndc) and 9, 9′-dihexyl-2, 7-di(pyridin-4-yl)fluorene (hfdp) reacted with Co²⁺ ions and Cd²⁺ ions to form two coordination polymers, [Co(hfdp)(ndc)(H₂O)]·DMA}_n (1) and {[Cd(hfdp)(ndc)(H₂O)]·DMA}_n (2), respectively (DMA=N, N-dimethylacetamide). Single-crystal X-ray diffraction analyses showed that both complexes 1 and 2 contain similar structures. Topological analysis indicates that complexes 1 and 2 have a {4⁴·6²} planar structure. In addition, both complexes reveal good thermal stability and fluorescence sensing performance. They exhibited good sensitivity and selectivity towards 2, 4, 6-trinitrophenol (TNP) by fluorescent quenching. The limits of detection of 1 and 2 for TNP were 0.107 and 0.327 μmol·L^-1, respectively.
