摘　　要：以6-氯-5,12-萘并萘醌和对硝基苯酚为原料,合成了6-(4-硝基苯氧基)-5,12-萘并萘醌,通过元素分析、IR、1H NMR和EIMS对其结构进行了表征。研究表明:6-(4-硝基苯氧基)-5,12-萘并萘醌可以发生类似于苯氧基萘并萘醌的光异构化反应,trans-form的最大吸收峰出现在393 nm处,而ana-form在453 nm和482 nm处显示出特征双峰,并且在343、372和404 nm处有三个等吸光点。6-（4-Nitryl phenoxy）-5,12-naphthacenequinone was synthesized using 6-chloro-5,12-naphthacenequinone as the starting material and its structure was confirmed using elemental analysis and the IR, 1H NMR and MS spectra. The compound exhibits the similar photoisomerization performance with that of phenoxynaphthacenequinone. The trans-form had an absorption maximum at 393 nm, while the ana-form had two large absorption maxima at 453 nm and 482 nm. Three isosbestic points were observed at 343 nm, 372 nm and 404 nm.
