Cation transport using anthraquinone-derived lariat ethers and podands: the first example of electrochemically switched on/off activation/deactivation

Anthraquinone undergoes one- and two-electron reduction to form either radical anions or dianions. When a crown-ether-type macrocycle or a polyethyleneoxy side chain is attached, the reduced aromatic and the oxygen donor groups cooperate to bind the cation. Binding of Li super(+) or Na super(+) is g...

Description
Summary:Anthraquinone undergoes one- and two-electron reduction to form either radical anions or dianions. When a crown-ether-type macrocycle or a polyethyleneoxy side chain is attached, the reduced aromatic and the oxygen donor groups cooperate to bind the cation. Binding of Li super(+) or Na super(+) is greater when anthraquinone is reduced because there is a charge-charge interaction between it and the cation. This property has been used to facilitate transport.
