Abstract: Two distinct morphologies of Cu₂(Salen)₂ nanomaterials were prepared using antisolvent precipitation method and solvothermal method, respectively. The structures and morphologies were characterized via infrared spectroscopy (IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Additionally, the molecular structure and coordination of the compound were analyzed using Olex2 software. This comprehensive experiment involves organic synthesis, coordination chemistry, nanomaterial preparation and characterization, and the application of crystallographic software, effectively bridging fundamental theory with modern technological applications. It emphasizes not only the reinforcement of basic knowledge, but also cultivates students’ innovative ability and comprehensive quality. The integration of cutting-edge scientific research into experimental teaching practice aims to create a synergistic effect that enhances both teaching and research, potentially establishing a beneficial cycle.
