摘　　要：介绍了一个综合化学实验。通过乌尔曼缩合反应合成一种具有电致变色性能的三苯胺衍生物。利用红外光谱、核磁共振氢谱、循环伏安法对化合物的结构及电化学性能进行表征。通过将电化学工作站和紫外-可见分光光度计联机进行光谱电化学测试,深入研究该化合物的电致变色性能。本实验充分体现了"合成—表征—分析"的科研思维模式,并打破了传统的单独仪器测试方式,在让学生了解合成化学知识和前沿学术研究的同时,提高学生的基本实验技能和综合运用学科知识的能力。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.
