摘要:

通过学生熟悉的羟醛缩合反应制备共价有机聚合物(COP)荧光材料;指导学生在实践中深化对理论知识的理解,学会自主思考和利用多种仪器分析荧光材料性质;引导学生发挥想象力,将荧光材料应用到与生活息息相关的信息加密中——“去伪存真”,体验化学的魅力。

Abstract:

Covalent organic polymers (COPs) fluorescence materials are prepared by aldol condensation reaction, which is familiar to students. This experiment is intended to guide students to deepen the understanding of theoretical knowledge in practice, and learn to think independently and analyze the properties of fluorescent materials by using a variety of instruments. We hope this experiment can stimulate students' imagination, make students to apply fluorescent materials to information encryption closely related to life — "eliminate the false and preserve the true", and experience the charm of chemistry.

Key words: Experimental design, Fluorescent materials, Aldol condensation, Information encryption
