(Chemical Equation Presented) A supramolecular propeller: A trinuclear EuIII helix with six chiral bipyridine-carboxylate ligands self-assembles with complete diastereoselectivity (see graphic; Eu green, O red, N blue). Ground-and excited-state chiroptical properties of this red-emissive complex reflect the helical arrangement of the ligands around the metallic core.
