  • Publication number: 20140051878
    Abstract: The invention relates to new metal complexes having N-aminoamidinate ligands, more particularly metal complexes having N,N?-bis(dimethylamino)acetamidinate, N,N?-bis(dimethylamino)formamidinate, N-dimethylaminoacetamidinate or N-dimethylamino-N?-isopropyl-acetamidinate ligands as well as to their preparation and use. The metal complexes are characterized by a five-membered chelate ring. The metal complexes are formed with the metals from the main groups of the PTE, but also with transition-group elements such as tantalum (Ta), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu) or zinc (Zn), and also with precious metals such as palladium (Pd). The complexes of the invention find use as precursors for the preparation of functional layers by means of gas-phase thin-film processes such as CVD, MO-CVD and ALD. Additionally they may be used as catalysts for olefin hydroamination and for olefin polymerization.

  • Patent number: 6518445
    Abstract: The methylaluminoxane composition (MAOC) is a solid at 25° C. that has a total aluminum content of about 39 to 47 wt %. The MAOC is either free of aluminum as trimethylaluminum (TMA) or if TMA is present, not more than about 30 mole % of the total aluminum in the MAOC is TMA. In the solid state the MAOC contains no more than about 2000 ppm (wt/wt) of aromatic hydrocarbon. The cryoscopic number average molecular weight of MAOC as determined in benzene is at least about 1000 amu, and the MAO has sufficient solubility in n-heptane at 25° C. to provide a solution containing 4 to as high as 7.5 wt % or more of dissolved aluminum. By vacuum distilling a solution of ordinary MAO in aromatic hydrocarbon long enough under proper conditions, MOAC is formed.

  • Patent number: 6428912
    Abstract: An improved multilayer light emitting device includes novel compounds for use as the electron transporting layer. In particular, the novel compounds are novel aluminum cheltates (e.g. tris(9-oxidophenalenone) aluminum [Al(9-opo)3] and tris(6-oxidobenzanthrone) aluminum [Al(6-obao)3]. These compounds are electron acceptors having improved thermal stability while in most cases and in most applications maintaining comparable efficiencies. When negatively biased, electrons are infected into the electron transporting layer. The concurrent positive bias on the anode in relation to the cathode causes holes to be injected from the cathode into the hole transporting layer. Electroluminescence is produced and confined generally near the interface between these electron and hole transporting layers an a result of the recombination of the electron and hole pairs.
