摘要: 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。 |

Abstract: Based on the photo-induced electron transfer(PET) mechanism, a redox-active fluorescent molecular bistable switch was obtained with ferrocene as a reversible redox-control of PET and fluorophore anthracene as signaling unit. The fluorophore emission behaviors were studied under different conditions. With various chemicals as input signals and emission intensity under different conditions as output signals, the protonation and oxidation were used to realize the molecular logic function. The inputs and corresponding outputs give an excellent correlation with the truth table for a digital AND logic gate at molecular level. |
Keywords: ferrocene fluorescence AND logic gate redox-active PET process |
