摘　　要：光致变色材料因其独特的变色机制而受到研究者关注。螺噁嗪光致变色体系性能较为优异,但抗疲劳性仍难以满足应用需求。本文从温度、光照条件、氧含量及氧存在状态等角度入手,探究螺噁嗪光致变色分子抗疲劳性的影响因素,并确定单重态氧是导致其失活的关键因素。Photochromic materials have attracted researchers’attention because of their unique discoloration mechanism.Spirooxazine photochromic system has excellent properties,but its fatigue resistance is still difficult to meet the application requirements.In this paper,the factors affecting the fatigue resistance of spirooxazine were studied from the perspectives of temperature,light conditions,oxygen content and oxygen existence state,and it was determined that singlet oxygen was the key factor leading to its inactivation.

关 键 词：螺噁嗪 光致变色 抗疲劳性 单重态氧
