Methylaluminoxane compositions, enriched solutions of such compositions, and the preparation thereof
Patent number: 6518445Abstract: 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.Type: GrantFiled: December 15, 2000Date of Patent: February 11, 2003Assignee: Albemarle CorporationInventors: Noel H.

Patent number: 6428912Abstract: 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.Type: GrantFiled: September 30, 1998Date of Patent: August 6, 2002Assignee: Agere Systems Guardian Corp.Inventor: Robert C. Haddon
