介绍了一个荧光光谱方面新的实验项目：以苝和六苯基噻咯作为发光物质的特征分子，通过测定其不同聚集状态下的荧光光谱，观察聚集荧光淬灭ACQ（aggregation-caused quenching）和聚集诱导发光AIE（aggregation-induced emission）两种不同的发光现象；利用晶体学数据库CCDC（Cambridge Crystallographic Data Centre）检索特征分子的晶体结构，从分子晶体结构层面分析AIE和ACQ发光现象产生的原因，在此基础上探讨不同发光机制和分子状态的关系。论文详细描述了实验的设计思想、实验内容和实验结论，并结合教学过程，分析了该实验在开阔学生视野、提高认知水平及培养科研素养等方面所取得的教学效果。
