A supramolecular propeller : A trinuclear Eu III 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.
