Two novel asymmetrical diarylethenes with an imidazole-containing substituent have been synthesized. The two diarylethenes exhibited favorable photochromism and functioned as fluorescence switches upon alternating ultraviolet and visible light irradiation. These two compounds could also serve as highly selective ‘naked-eyes’ colorimetric sensors for Cu2+. Furthermore, the diarylethene with a 1H-phenanthro[9
已经合成了两个具有含咪唑取代基的新型不对称二芳烃。两种二芳烃显示出良好的光致变色性,并在交替的紫外线和可见光照射下起荧光开关的作用。这两种化合物还可以用作Cu 2+的高选择性“裸眼”比色传感器。此外,具有1 H-菲并[9,10- d ]咪唑单元的二芳基乙烯对Sn 2 +,Al 3+和Cr 3+具有选择性。具有明显的荧光变化。基于此特性,通过使用化学物质和光的组合刺激作为输入并以444 nm的荧光强度作为输出来构建逻辑电路。
