Two coumarin-based spiropyran derivatives were synthesized and characterized in two steps to explore their photochromic properties. Both prepared compounds are sensitive to UV light and change colors upon irradiation. The resulting photogenerated zwitterions revert to the original compounds while being heated. A new family of organic photochromic colorants is introduced.
合成了两种基于香豆素的螺吡喃衍生物，并分两步对其进行了表征，以探究它们的光致变色特性。所制备的两种化合物均对紫外光敏感，照射后会变色。生成的光生两性离子在加热时会恢复为原始化合物。引入了一个新的有机光致变色着色剂家族。
