针对螺噁嗪化合物光致变色的实验现象,通过分子力学和量子化学理论计算表明螺环分子受光照后开环形成能量相近的酮式结构,呈蓝色.停止光照后又回复至张力能相对较小的螺环结构,蓝色褪去.
According to the experimental results of photochromism of spirooxazine compounds, the calculation of molecular mechanics and quantum chemical theory shows that the spirocyclic molecules are ring-opened to form a ketone structure with similar energy and blue color. After stopping the light and returning to the tension, Smaller spiro structure, blue faded.
