New heterocyclic TTF compounds 1a-c and 2 with an azobenzene moiety were described. The oxidation potential of 1a could be reversibly modulated by alternating UV and visible light irradiation. As a result, a molecular switch with UV/visible light as the inputs and the electrochemical signal as the output was achieved. Moreover, it was found that the influence of the azobenzene photoisomerization on the electronic property of the TTF unit became stronger with shorter spacers in compounds 1a-c.
报道了新型含偶氮苯部分的杂环四硫富瓦烯（TTF）化合物1a - c和2。通过交替进行紫外光和可见光照射，1a的氧化电位能够被可逆地调节。结果，实现了一个以紫外光/可见光作为输入、电化学信号作为输出的分子开关。此外，还发现对于化合物1a - c而言，随着间隔基团变短，偶氮苯光异构化对TTF单元电子性质的影响变得更强。
