In one embodiment, the first and second metal centers each have coordination numbers of at least 3, and more preferably each have coordination numbers of 4. In one embodiment, photoactive ligands are coordinated to the first and second metal centers. In one embodiment, there are no photoactive ligands. In one embodiment, a charge neutral bi-nuclear emissive material is provided.

    摘要: An organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between and electrically connected to the anode and the cathode. The emissive layer further comprises a compound having two metal centers, in which each metal has an atomic weight greater than 40. A bridging ligand, small molecule, or polymer is coordinated to both metal centers, and at least one photoactive ligand is bound to each metal. In one embodiment, the transition dipole moment of the photoactive ligand bound to the first metal is orthogonal to the photoactive ligand bound to the second metal. In another embodiment, the first metal center and the atoms of the bridging ligand that are coordinated to the first metal center form a plane and the atoms of the bridging ligand that are coordinated to the second metal center form another plane, and the planes form an angle that is between about 80 degrees and 100 degrees. In another embodiment, the bridging ligand is diacetylacetonate. In another embodiment, a polymer or small molecule is coordinated to both metals, and the metal-ligand complex for the first metal center is different from the metal-ligand complex for the second metal center.

    摘要: A series of organometallic complexes and the singlet oxygen sensitization properties of these complexes are provided. Complexes with acetylacetonate ligands give singlet oxygen quantum yields near unity, whether exciting the ligand-based state or the lowest energy excited state (MLCT+3LC). The singlet oxygen quenching rates for these β-diketonate complexes are small, roughly three orders of magnitude slower than the corresponding phosphorescence quenching rate. Similar complexes were prepared with glycine or pyridine tethered to the Ir(III) center (i.e. (bsn)2Ir(gly) and (bt)2Ir(py)Cl, where gly=glycine, and py=pyridine). The glycine and pyridine derivatives give high singlet oxygen yields.
