imidazole ring greatly affect the optical properties. The light-emitting properties can be easily tuned from blue light-emitting to yellow light-emitting fluorescence by varying the nature of the heterocycle or by simple modification of structures, which provides a new strategy for the design of novel fluorescent switches. Moreover, Cu2+, Hg2+, and Fe3+ greatly affect the fluorescence properties of diarylethene
合成了一系列新的引入不同杂环的二芳烃及其N-甲基化衍生物,并通过NMR,MS和元素分析对产物进行了表征。每种化合物在紫外线照射下均表现出光致变色和“开启”荧光特性。已经发现,连接到咪唑环的杂环的性质和咪唑环的甲基化都极大地影响光学性质。通过改变杂环的性质或通过简单的结构修饰,可以容易地将发光性质从发蓝光的荧光调整为发黄光的荧光,这为新颖的荧光开关的设计提供了新的策略。此外,Cu 2 +,Hg2+和Fe 3+在光平稳状态下极大地影响了二芳基乙烯4的荧光性质,因此这些系统可能会部署在新型分子传感器中,以通过荧光识别来检测此类阳离子。
