Abstract: A new coupled transport system, using calixarene derivatives as the cationic carriers and nickel complex of multi-sulfur 1,2-dithiolene[Ni(dmit)2] as the electron carrier, was reported in this paper. The reducting phase (source phase) contains sodium dithionite as reducing agent; the oxidation phase (receiving phase) contains potassium ferricyanide as oxidizing agent. Driven by the redox gradient, the coupled transports of electrons and metal cations were thus realized. The impacts of the cationic carriers and the electronic carrier on the coupled transport were studied. In addition, the mechanism of transport of electron-cation symport was discussed.
