A new series of doublearmed diaza-crown ethers, bearing pyridino- and quinolino-arm groups, were first shown to effectivelybind and transport some “transition metal cations” via three-dimensional complexations, which were not attained by common crownethers.

Macrocyclic polyethers having two ‘arms’ available for cation binding provide new and characteristic transport abilities, based on their unique ligand topology, which not attained in the usual crownether and cryptand systems.
