本文在化学离子易位和（超）分子逻辑中加入了时域。当用2-氰基-2-苯基丙烷酸(4)作为化学燃料处理自分选的[Zn(1)](2+) + [Li(2)](+) + 3（由六环素1、纳米开关2、发光团3组成）时，1的质子化首先引起Zn2+级联易位，然后是Li+，导致系统[H(1)](+) + [Zn(2)](2+) + [Li(3)]（+）缓慢逆转回初始状态。使用锂敏感探针3，跟踪锂脉冲的动力学演变，观察其颜色和发光的变化。通过产生时间编码的SOS莫尔斯信号，并在两个不同的与门中实现时域，举例说明了燃料与锂脉冲结合的实用性。
The present paper adds the time domain to chemical ion translocation and (supra)molecular logic. When the self-sorted system of [Zn(1)](2+) + [Li(2)](+) + 3 (composed of hexacyclen 1, nanoswitch 2, luminophore 3) was treated with 2-cyano-2-phenylpropanoic acid (4) as a chemical fuel, protonation of 1 entailed a cascade translocation of first Zn2+, then Li+, resulting in the system [H(1)](+) + [Zn(2)](2+) + [Li(3)](+) that slowly reversed back to the initial state. The kinetic evolution of the lithium pulses was followed by changes in color and luminescence using the lithium-sensitive probe 3. The utility of fueling in combination with lithium pulses was exemplified among others by generating time-encoded SOS morse signals and implementing the time domain in two distinct AND gates.
