Patent number: 6992202Abstract: A single source precursor for depositing ternary I-III-VI2 chalcopyrite materials useful as semiconductors. The single source precursor has the I-III-VI2 stoichiometry “built into” a single precursor molecular structure which degrades on heating or pyrolysis to yield the desired I-III-VI2 ternary chalcopyrite. The single source precursors effectively degrade to yield the ternary chalcopyrite at low temperature, e.g. below 500° C., and are useful to deposit thin film ternary chalcopyrite layers via a spray CVD technique. The ternary single source precursors according to the invention can be used to provide nanocrystallite structures useful as quantum dots. A method of making the ternary single source precursors is also provided.Type: GrantFiled: October 31, 2003Date of Patent: January 31, 2006Assignees: Ohio Aerospace Institute, The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Kulbinder K.

Patent number: 6909009Abstract: Novel polynuclear organometallic complexes useful as catalysts for the reversible deshydrogenation of alkanes and alkane group are disclosed. The novel compounds comprise a first transition, a second transition metal p-bonded to an ?5-aromatic ligand, and a pincer ligand. The pincer ligand comprises a 6p-electron aromatic ring having at least 2 ring atoms in an 1, 3 relationship bonded each to a neutral Lewis base through a bridge, the bridge being a diradical. The pincer ligand binds the first transition metal through each of the Lewis bases and through the ring atom adjacent to both Lewis bases and p-coordinates the second transition metal through all aromatic ring atoms. The first transition metal may also bond to 2 or 4 hydrogen atoms.Type: GrantFiled: March 8, 2002Date of Patent: June 21, 2005Inventor: Avtandil Koridze

Patent number: 6878838Abstract: Chiral porous zirconium phosphonates containing metal complex moieties are provided, synthesized via a molecular building block approach, and characterized by a variety of techniques including TGA, adsorption isotherms, XRD, SEM, IR, and microanalysis. These hybrid solids may be used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with remarkably high e.e. values of up to 99.2%. Similarly prepared chiral porous solids may be used for asymmetric hydrogenation of ?-keto esters with e.e.'s of up to 95%. The solid catalysts can also be easily recycled and reused multiple times without the loss of activity and enantioselectivity. Ready tunability of such a molecular building block approach allows the optimization of these hybrid materials to provide practically useful heterogeneous asymmetric catalysts.Type: GrantFiled: March 24, 2003Date of Patent: April 12, 2005Assignee: The University of North Carolina at Chapel HillInventors: Wenbin Lin, Aiguo Hu, Helen L.
