A ligand-stabilized tetrameric zinc(II) cluster with high-efficiency emission from both singlet and triplet excited states for electroluminescent devices
Communication: Blue photoluminescence with high quantum efficiency is emitted by both the singlet and triplet excited states of the 7-azaidolate-containing tetrameric zinc(Ir) cluster (Zn4O(AID)(6)) (see Figure) in solution and in the solid state at room temperature. A blue light-emitting diode with Zn4O(AID)(6) as the active layer is shown to have an electroluminescence efficiency of 0.8 %.
