摘要
设计合成了含有萘酚吡喃和姜黄素的光致变色荧光开关分子.在聚甲基丙烯酸甲酯(PMMA)薄膜中基于能量转移机理通过萘酚吡喃的光致变色行为实现了对姜黄素荧光强度的调节,即荧光的"开/关".荧光图像变化进一步证实了萘酚吡喃的光致变色开关环反应能够可逆地调节姜黄素的荧光强度.
The photochromic fluorescence switching based on the naphthopyran-curcumin compound was designed and synthesized.The fluorescence intensity of curcumin can be modulated between “on” and “off” by the photochromic behaviors of naphthopyran in the doped PMMA film based on the photoinduced energy transfer mechanism.The fluorescent images further proved that the ring-open reaction of naphthopyran can modulate the fluorescent intensity of curcumin.
