报道了一个基于光致电子转移(PET)机理的双稳态荧光分子开关,其中具有氧化还原活性的二茂铁基团作为荧光团蒽PET过程的氧化还原控制单元,通过双Schiff碱C=N键与蒽相连。研究了不同条件下蒽的荧光发射行为。以不同的化学试剂作为体系的输入信号,以不同的荧光发射强度作为输出信号,利用荧光分子开关的质子化反应和氧化反应实现了一个分子水平的逻辑功能。输入信号及其相应的输出结果在分子水平上符合数字逻辑与门的真值表。 Reported a bistable fluorescent molecular switch based on the mechanism of photo-electron transfer (PET), in which a redox-active ferrocene group as the redox control unit of the fluorophore anthracene PET process was synthesized by double Schiff base C = N Bond with anthracene. Fluorescence emission behavior of anthracene under different conditions was studied. With different chemical reagents as the input signal of the system, different fluorescence emission intensity as the output signal, the use of fluorescent molecular switch protonation and oxidation reaction to achieve a molecular level of logic. The input signal and its corresponding output match the truth table of digital logic and gates at the molecular level.
