Abstract: Synthesis of redox switched ionophores 1-[1-anthraquinonyloxy) 3, 6 dioxaoctane-8-methane (A1) and 1-[1-anthraquinonyloxy] 3 oxapentane-5-methane (A2) has been reported. These ionophores have been used as carriers in liquid membrane transport and extraction studies of alkali and alkaline earth metal ions. The sequence of metal ions extracted and transported in oxidised and reduced state by ionophore A1 is: Ca2+>K+>Li+>Mg2+ and Li+>K+>Ca2+>Mg2+ ┬árespectively. The order of ex traction and transport of metal ions with respect to ionophore A2 is Li+>K+>Ca2+ and Ca2+>K+>Li+ respectively. Ionophore A1 is selective for Ca2+ while ionophore A2 is selective for Li+ ions. This selectivity may be used in ion selective electrode and redox switch able devices.
