摘　　要：近年来,通过以共轭方式引入识别基团,使二芳基乙烯衍生物具有离子调控光开关能力的特性引起了学者们的广泛关注。然而,如何设计和合成通过离子进行多梯度调控光开关能力的简单化合物仍是一个亟待解决的难点。我们设计并合成了一种通过希夫碱与硫代甲肼基团连接的新型二芳基乙烯分子DTES,其具有典型的光致变色性能,同时对Cu^(2+)和Ni^(2+)产生明显的光谱响应特性。进一步研究发现,能够通过与Cu^(2+)、Ni^(2+)、Zn^(2+)或Sn^(2+)的特异络合来多梯度调控DTES的光开关特性。基于这些光响应特性,我们设计了一个具有四输入信号和三输出信号的分子电路用来完成复杂逻辑运算。In recent years,the introduction of recognition moieties to diarylethenes through conjugation enables diarylethenes to possess ions-regulated photoswitching characteristics,which has attracted extensive attention of scholars.However,how to design and synthesis of simple compounds with the ability of ions-regulated multi-gradient photoswitching characteristics still remains challenging.In this work,we designed and synthesized a new type of diarylethylene molecule DTES with thiomethylhydrazine as recognition moiety and Schiff base as linker.It exhibits typical photochromic properties,and spectroscopically responds to Cu^(2+)and Ni^(2+)specifically.Furthermore,it is found that the photochromic properties of DTES can be regulated by specific complexation with Cu^(2+),Ni^(2+),Zn^(2+)and Sn^(2+)in a multi-gradient mode.Based on these photo-responsive characteristics,we designed a molecular circuit with four inputs and three outputs to complete complex logic operations.
