A novel photochromic diarylethene dimer with a bis(benzylene)amine-linked naphthalimide unit was synthesized, and its photochemical properties were systematically studied. Upon irradiation with ultraviolet light, a singly-closed isomer and a fully-closed isomer were reversibly formed, which were confirmed by the results of Nuclear Magnetic Resonance spectroscopy (NMR) and High-Performance Liquid Chromatography (HPLC). Additionally, the diarylethene dimer could be used as a multi-addressable fluorescence switch when triggered by light, proton, and metal ions. Moreover, a logic circuit was constructed with the unimolecular platform by using the fluorescence intensity at 445 nm as output and appropriate combinational stimuli of UV light, Al³⁺, and EDTA as inputs.

合成了具有双（亚苄基）胺连接的萘二甲酰亚胺单元的新型光致变色二芳基乙烯二聚体，并对其光化学性质进行了系统的研究。在用紫外线照射时，可逆地形成单封闭的异构体和全封闭的异构体，这通过核磁共振光谱法（NMR）和高效液相色谱法（HPLC）的结果得以证实。另外，当被光，质子和金属离子触发时，二芳基乙烯二聚体可用作多址荧光开关。此外，通过使用在445 nm处的荧光强度作为输出并使用UV光，Al ³⁺和EDTA的适当组合刺激作为输入，使用单分子平台构建逻辑电路。
