Abstract: This study presents a preliminary investigation of anthracene-based supramolecular polymer materials exhibiting vapochromic properties within the context of innovative chemical experiments. The fabricated “chameleon” patterns demonstrate orange-red fluorescence in their solid state and exhibit rapid color transitions to yellow or green fluorescence upon exposure to specific vapors. The experimental framework encompasses the synthesis of supramolecular polymer materials, fluorescence characterization, and vapor response evaluation, effectively incorporating the fundamental principles of molecular recognition and stimulus-responsive behavior from supramolecular chemistry into practical teaching applications. Through direct observation of fluorescence color transitions and subsequent spectral data analysis, students gain profound insights into the structure-property relationships of intelligent materials. This research successfully integrates cutting-edge scientific advancements with fundamental experimental practices, thereby enhancing students' comprehensive experimental competencies and innovative capabilities.
