multi-stimuli gating function in a unimolecular platform has rarely been addressed. Herein, a new strategy to realize multi-stimuli gated photochromic function was devised relying on a simple Schiff-based diarylethene derivative. The compound shows no photoswitching properties in solution under irradiation with any wavelength of light. It is noteworthy that mecury(II) ions, water and protons can trigger its photo-reactivity
门控光致变色系统由于其在光电领域的优势而引起了科学研究的极大兴趣,而单分子平台中的多激励门控功能却很少得到解决。在此,基于简单的基于席夫(Schiff)的二芳基乙烯衍生物,设计了实现多刺激门控光致变色功能的新策略。该化合物在任何波长的光照射下在溶液中均未显示出光开关性能。值得注意的是,汞(II)离子,水和质子可以分别以不同的吸收变化独立地触发其光反应性。因此,在单分子平台的基础上,制造了具有四个输入的分子逻辑电路,包括汞离子,水,质子和紫外线。暗示了在多控光电开关中的应用前景。这些结果对于具有多种刺激反应的光开关的进一步发展可能是有价值的。
