A new-synthesized diarylethene with near-infrared fluorochrome unit exhibited excellent photochromism under the irradiation of UV light (297 nm) and visible light (λ > 500 nm). When Cu was added to the diarylethene solution, a fluorescent emission band centered at 736 nm appeared, indicating that the emission peak wavelength of compound is in near-infrared region. According to data of NMR, MS and other experiments, the complex ratio of the target compound to Cu was 1:1 in the CHCN-HO solution (v/v = 9:1) with a limit of detection (LOD) of 0.10 μM. Furthermore, a logic circuit was constructed with four input signals (ultraviolet stimulus, visible light stimulus, Cu and EDTA) and one output signal (fluorescent intensity at 736 nm).
一种新合成的二芳基乙烯，带有近红外荧光团单元，在紫外光（297nm）和可见光（λ＞500nm）的照射下表现出优异的光致变色性能。当 Cu 被添加到二芳基乙烯溶液中时，在 736nm 处出现一个荧光发射带，表明化合物的发射峰波长在近红外区域。根据 NMR、MS 等实验数据，在 CHCN-HO（v/v=9:1）溶液中，目标化合物与 Cu 的络合比为 1:1，检测限（LOD）为 0.10μM。此外，构建了一个由四个输入信号（紫外刺激、可见光刺激、Cu 和 EDTA）和一个输出信号（736nm 处的荧光强度）组成的逻辑电路。
