  • Patent number: 8232546
    Abstract: In one embodiment of the present invention, a novel fused polycyclic aromatic compound of the present invention is (a) a compound including a benzodichalcogenophenobenzodichalcogenophene (BXBX) skeleton further having an aromatic ring(s) located outside the BXBX skeleton, or (b) a compound including a BXBX skeleton in which a benzene ring is substituted with a heterocyclic ring. The compound can strengthen intermolecular interaction due to greater ? electron orbits. This improves an electron field effect mobility of an organic semiconductor device that is manufactured by use of the compound as an organic semiconductor material. Further, since the number of fused rings included in the compound is small, the compound does not cause problems that generally occur in compounds having an extremely large number of fused rings, i.e., poor solubility in solvent and poor atmospheric stability due to high affinity to oxygen.

The quantified amount can then be used to determine the amount of the compound of interest that bound to the hERG K+ channel. A selenium analog of any competitive inhibitor of the hERG K+ channel may be used according to the present invention, including but not limited to selenium analogs of the small molecule dofetilide; the peptide BeKm-1; or a combination of both.

  • Patent number: 7371429
    Abstract: A Te precursor containing Te, a 15-group compound (for example, N) and/or a 14-group compound (for example, Si), a method of preparing the Te precursor, a Te-containing chalcogenide thin layer including the Te precursor, a method of preparing the thin layer; and a phase-change memory device. The Te precursor may be deposited at lower temperatures for forming a Te-containing chalcogenide thin layer doped with a 15-group compound (for example, N) and/or a 14-group compound (for example, Si). For example, the Te precursor may employ plasma enhanced chemical vapor deposition (PECVD) or plasma enhanced atomic layer deposition (PEALD) at lower deposition temperatures.
