摘要: 为响应国家“101计划”对拔尖创新人才培养的要求,本文针对传统“季膦盐的合成”实验存在的溶剂毒性高、耗时长、体验感差等问题,采用水相一步法绿色合成乙基三苯基溴化膦,避免使用有毒溶剂,将反应时间缩短至2.5 h、产率提升至75%,并进一步制备了具有力致发光性能的锰配合物。教学上设计为基础实验(5.5学时)与综合实验(9.5学时)两个模块,构建了一体化的实验教学体系。本文将原有实验升级为有机-无机融合、兼具实践性与前沿性的综合实验,为打造高质量核心实验课程提供了参考。

Abstract: In response to China’s “101 Plan” for cultivating top-tier innovative talents in fundamental disciplines, this study addresses key limitations in traditional phosphonium salt synthesis experiments, including high solvent toxicity, lengthy reaction times, and poor operational experience. We developed an environmentally friendly aqueous one-step synthesis method for ethyltriphenylphosphonium bromide, eliminating toxic solvents while reducing reaction time to 2.5 h and improving yield to 75%. The synthesized phosphonium salt was subsequently used to prepare a mechanoluminescent manganese complex. The pedagogical design incorporates two modules: a foundational experiment (5.5 credit hours) and an advanced comprehensive experiment (9.5 credit hours), establishing an integrated experimental teaching system. This work transforms a conventional experiment into an interdisciplinary, practical, and cutting-edge comprehensive experiment, providing valuable insights for developing high-quality core experimental courses.
