进行逻辑运算的分子是分子信息处理和计算的先决条件。我们12，13和其他人14 -16先前已经报道了受体分子，可以被认为是通过将离子键合或更复杂的分子识别过程与光子（荧光）信号耦合来执行简单的逻辑操作：在这些系统中，化学结合（“输入”）导致受体荧光强度（“输出”）的变化。在这里，我们描述了一个受体（图1中的分子（1）），它作为一个具有两个输入通道的逻辑设备运行：荧光信号取决于分子是否结合氢离子，钠离子或两者兼而有之。该分子器件的输入/输出特性与与门的输入/输出特性相对应。
MOLECULES at perform logic operations are prerequisites for molecular information processing and computation1-11. We12,13 and others14-16 have previously reported receptor molecules that can be considered to perform simple logic operations by coupling ionic bonding or more complex molecular-recognition processes with photonic (fluorescence) signals: in these systems, chemical binding (the 'input') results in a change in fluorescence intensity (the 'output') from the receptor. Here we describe a receptor (molecule (1) in Fig. 1) that operates as a logic device with two input channels: the fluorescence signal depends on whether the molecule binds hydrogen ions, sodium ions or both. The input/output characteristics of this molecular device correspond to those of an AND gate.
