研究了以四硫富瓦烯单元为线状电子给体和环二（百草枯对苯撑）四价阳离子电子受体在乙腈溶液中自组装生成的准轮烷的电化学和光谱性质。我们表明，a）可逆的脱螺纹/rethreading循环的准轮烷可以通过氧化和连续还原的电子供体线或还原和连续氧化的电子接受四价环蕃，和B）由于这种特殊的行为，输入（电化学）/输出（吸收光谱）特性的这种分子水平的系统对应于那些的XNOR逻辑门。
The electrochemical and spectroscopic properties of a pseudorotaxane formed in acetonitrile solution by self-assembly of a wire-type electron donor based on the tetrathiafulvalene unit and the cyclobis(paraquat-p-phenylene) tetracationic electron acceptor have been investigated. We show that a) reversible dethreading/rethreading cycles of the pseudorotaxane can be performed by either oxidation and successive reduction of the electron-donor wire or reduction and successive oxidation of the electron-accepting tetracationic cyclophane, and b) because of this special behavior, the input (electrochemical)/output (absorption spectrum) characteristics of this molecular-level system correspond to those of an XNOR logic gate.
