摘 要:合成了3种新型的螺噁嗪化合物,并通过IR,MS,1H NMR对其结构进行了表征。研究了1位和9'位上取代基对螺噁嗪光致变色性能的影响;不同溶剂对螺噁嗪最大吸收波长的影响;对螺噁嗪的热褪色速率进行了动力学的研究。结果表明,当螺噁嗪1位的取代基为柔性结构,9'位连接能形成更稳定共轭体系的取代基时有利于开环体热稳定性的提高。Three kinds of novel spirooxazines had been synthesized. The structures of spirooxazines were confirmed on the basis of IR,MS,IH NMB. The effects of substituent groups at 1 and 9' position on their photochromism properties were investigated. The roles of maximum absorption wavelength in the visible region in different solvents were studied. We had also studied the kinetics of the thermal decay process of spirooxazines in ethanol solution. The results showed that replacing 1 position with flexible substituent groups, or 9' position with groups forming a more stable conjugated system was conducive to improvement of the thermal stability of open-loop body(PMC).
