There are three kinds of energy-supplied modes to drive artificial molecular machines: chemical stimulation, electrochemical input and light stimulation. The basic principle of acid/base-controlled (or pH-operated) method is to change the chemical properties of components in the system by adjusting pH of the solution via adding acid/base compounds, to realize the movements of components, which belongs to chemical stimulation mode. The acid/base controlled method has been one of the most useful energy-driven modes for artificial molecular machines. This article summarizes the recent studies on acid/base- controllable molecular machines or molecular switches. The synthesis and operation of acid/base-controllable artificial molecular switches and molecular machines based on crown ethers and other macrocyclic hosts are reviewed. They exhibited great potential in the applications for information storage materials, electronic devices, and drug delivery.

Key words: molecular machines, molecular recognition, crown ethers, cryptands, host-guest compounds, rotaxanes, supramolecular chemistry, molecular devices
