Abstract: A comprehensive organic experiment, focusing on the synthesis and photochromic properties of 3,3-diphenyl-3H-benzo[f]chromene (3H-NP), was developed by incorporating Claisen rearrangement, photochemical reactions, and solid-phase synthesis. The product was synthesized using both liquid-phase and solid-phase methods, and the impact of different synthetic approaches on yield was compared. The photochromic properties of the product were investigated using UV-Vis absorption spectroscopy. By integrating the scientific research process into teaching practice, this experiment aims to foster scientific literacy and innovation skills among undergraduate students.
