Abstract A novel electrochromic (EC) compound of N,N-di(4-methoxyphenyl)-2-amino-9,9-dimethylfluorene was synthesized by using triphenylamine derivative as a precursor via Ullman reaction. The structure and electrochemical properties of the compound were characterized by infrared spectroscopy, nuclear magnetic resonance spectroscopy, and cyclic voltammetry. The EC performance of the compound was deeply investigated by spectroelectrochemistry with combining an electrochemical workstation with an UV-visible spectrum. This work fully reflects the scientific thinking mode of “synthesis-characterization-analysis” and breaks the traditional characteristic mode of single instrument. While making students understand the knowledge of synthetic chemistry and frontier academic research, it also improves students’ basic experimental skills and ability of applying subject knowledge comprehensively.
