Coordination properties of a polyamine cryptand with two different binding moieties. A case of a pH-modulated antenna device based on a new Eu(III) cryptate complex

Research has been conducted on the protonation and alkali- and alkaline-earth-metal coordination by the dipyridine-containing cryptand L. The study of this coordination has been carried out via the potentiometric and spectroscopic measurements in aqueous solutions and the results are discussed.
