Description
Le-Hoang, Guénée, and Piguet report a chemistry study on how metal binding can steer the stacking of aromatic molecules. Their two-armed ligand binds rare-earth ions such as yttrium and europium. Binding charges the ligand and drives unlike rings to stack together. The stacks form paired units, in crystals and in solution.
Crystal work and titration tests confirmed that stacking in the ground state. Under light, the stacks formed excited pairs that change the glow given off. Three guest ring compounds, from electron-poor to electron-rich, probed the stacking further. Tuning such forces, the team shows, can reshape how a material gives off light.
