Ionophores which have the capacity to spontaneously assemble in solution are disclosed. These ionophores are composed of hydrogen-bonded monomers such as 5'-(t-butyl-dimethylsilyl)-2',3'-O-isopropylidine-isoguanosine, or 5'-(t-butyl- dimethylsilyl)-2',3'-O-isopropylidene-thio-isoguanosine. These ionophores self assemble in the presence of cesium ions, thereby forming complexes, each containing an ion. These ionophores are therefore useful for removing 137- cesium ions from nuclear waste.
La présente invention concerne des ionophores capables de s'assembler spontanément lorsqu'ils se trouvent en solution. Ces ionophores sont composés de monomères liés à l'hydrogène tels que la 5'-(t-butyl-dyméthylsilyl)-2',3'-O-isopropylidine-isoguanosine ou la 5'-(t-butyl-dyméthylsilyl)-2',3'-O-isopropylidène-thio-isoguanosine. Ces ionophores s'autoassemblent en présence d'ions césium, formant des complexes contenant chacun un ion. Ces ionophores sont par conséquent utilisés pour éliminer les ions césium 137 des déchets nucléaires.
