| 摘 要： | 以6-氯-5,12-萘并萘醌为起始原料,合成了9-苯氧基-并四苯5,6-bc]吡喃-2,8-二酮,通过元素分析、IR、1H NMR和E IM S对其结构进行了表征。研究表明：9-苯氧基-并四苯5,6-bc]吡喃-2,8-二酮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421 nm处,而ana-form在490 nm和524 nm处显示出特征双峰,并且在354、388和450 nm处有3个等吸光点。

| Abstract: | 9-Phenoxy-naphthaceno5,6-bc]pyran-2,8-dione 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 421 nm,while the ana-form had two large absorption maxima at 490 nm and 524 nm.Three isosbestic points were observed at 354 nm,388 nm and 450 nm. |
