6-(4-甲基苯氧基)-5,12-萘并萘醌的合成与光致变色性质

Synthesis and Photochromic Properties of 6-(4-Methylphenoxy)-5,12-naphthacenequinone

以6-氯-5,12-萘并萘醌为起始原料,合成了6-(4-甲基苯氧基)-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-甲基苯氧基)-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396 nm处,而ana-form在453 nm和482 nm处显示出特征双峰,并且在341、365和406 nm处有三个等吸光点。

6 - （4 - Methylphenoxy） - 5,12 - naphthacenequinone was synthesized using 6 - chloro - 5,12 - naph- thacenequinone as the starting material and its structure was confirmed using elemental analysis and the IR, ^1H NMR and MS spectra. The compound exhibited the similar photoisomerization performance with that of phenoxynaphthacenequinone. The trans - form had an absorption maximum at 396 nm, while the trans - form had two large absorption maxima at 453 nm and 482 nm. Three isosbestic points were observed at 341 nm, 365 nm and 406 nm, respectively.
