摘　　要：设计了一个4学时的无机化学实验,通过学习一种具有聚集诱导发光(AIE)特性的铜碘簇合物的合成及其在构筑长余辉发光材料中的应用,使学生掌握无机簇合物合成、晶体生长等技能,加深其对教材中配位化合物、簇合物、旋光异构体、杂化轨道等概念的认识与理解。同时,将AIE和长余辉发光这些化学研究前沿热点引入本科实验教学,通过有趣直观的化学现象,激发学生的学习热情。结合课堂讲解、文献阅读,引导学生探索化学现象背后的机理。本实验学时紧凑,所需的试剂仪器简单、成本低廉,适合在化学或相关专业的本科实验教学中推广。本实验符合教育部高等学校化学类专业教学指导委员会《化学类专业化学实验教学建议内容》关于“物质的合成与制备”中对于“簇合物”知识点的相关内容要求,丰富了传统无机实验课程内容。In this work,a 4-h inorganic chemistry experiment was designed.Herein,an aggregation-induced emission(AIE)copper iodine cluster was synthesized and used for the construction of long-afterglow emission material.Students can learn about the synthesis of cluster compound and the growth of crystal,and deepen the understanding of coordination compound,cluster compound,enantiomers,and hybrid orbital,among others.Meanwhile,by introducing AIE,which is a research hotspot,and long-afterglow emission,which is an interesting chemical phenomenon,the enthusiasm in learning of students will be aroused.Combining with classroom instruction and literature reading,students can also understand the mechanism behind the experiment.This experiment is compact,and the reagents and instruments used are simple and cost-effective,making it suitable for promotion in undergraduate experiment of chemistry or other related majors.This experiment fitted well with the requirement about“cluster compound”of“synthesis and preparation of compounds”in“chemical experiment teaching suggestions for chemistry majors,”which was issued by the national instruction committee of higher chemistry education of ministry of education.This experiment enriched the content of traditional inorganic chemistry experiment.
