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
