  • Publication number: 20120276687
    Abstract: The design and synthesis of six nickel charge transfer (CT) complexes are described herein. The six nickel CT complexes have a nickel center, two organic ligands coordinated with the nickel center to form a dianionic square planar supramolecule and an organic counter-cation. The ligands and counter-cations are selected to optimize properties, such as molecular alignment, film morphology, and molecular packaging. Described herein, the ligands can be 2,3-pyrazinedithiol (L1), 1,2-benzenedithol (L2) or 2,3-quinoxalinedithol (L3) and the counter-cations can be diquat (2,2?-ebpy) or methyl viologen (4,4?-mbpy). The six nickel CT complexes can also be utilized semiconductor devices, such as thin film transistors or inverters. Processes are also provided for the fabrication of semiconductors devices. The processes can include fabricating a substrate with a bilayer octadecylphosphonic acid (ODPA)/Al2O3 dielectric and applying one of the six nickel charge transfer (CT) complexes to the substrate.

  • Patent number: 8297334
    Abstract: A sliding panel includes multiple connecting/adjacent carrier tracks such as two/three/four carrier tracks while connectors of each carrier track are disposed in opposite directions or at intervals. Thus the multiple connecting/adjacent carrier tracks slide in parallel under the same channel. Moreover, the positions of each connector on top surface of respective carrier track are in alternating arrangement so as to allow runners of multiple connecting/adjacent carrier tracks being mounted inside the same channel simultaneously. The runners of the connecting/adjacent carrier tracks move inside the channel of a rail at the same time and the connecting/adjacent carrier tracks slide in parallel under the same channel. Therefore, the number of channels of the rail is decreased and the amount of material used for producing the rail is reduced. Furthermore, the rail can be designed to have two-step inner and outer rails for adjusting length of the rail.
