Two novel diarylethene derivatives containing imidazo [4,5-f] [1,10] phenanthroline have been efficiently synthesized. These molecules are sensitive to both light and chemical stimuli. Under sequential alternating UV–vis light irradiation and alkali/acid treatment, distinct differences in NMR, UV–vis, and fluorescent spectra were observed. Taking advantage of the variations in visible absorption and
已经有效地合成了两种新型的含咪唑并[4,5- f ] [1,10]菲咯啉的二芳基乙烯衍生物。这些分子对光和化学刺激均敏感。在连续交替的紫外可见光照射和碱/酸处理下,观察到NMR,紫外可见光和荧光光谱的明显差异。利用可见光吸收和荧光的变化,单个分子实现了具有两个光学输出的可逆四态分子开关。
