  • Publication number: 20140217375
    Abstract: Novel semiconducting polymers have been formed via the electron-induced cross-linking of orthocarborane B10C2H2 and 1,4-diaminobenzene. The films were formed by co-condensation of the molecular precursors and 200 eV electron-induced cross-linking under ultra-high vacuum (UHV) conditions. Ultraviolet photoemission spectra show that the compound films display a shift of the valence band maximum from ˜4.3 eV below the Fermi level for pure boron carbide to ?1.7 eV below the Fermi level when diaminobenzene is added. The surface photovoltage effect decreases with decreasing B/N atomic ratio. A neutron detector comprises the polymer as the p-type semiconductor to be paired with an n-type semiconductor.

    Abstract: The invention relates to an organic light-emitting diode (OLED) having an improved lifetime and improved transport of negative charge carriers. The organic light-emitting diode is based on an organic semiconductor material, in which the transport of negative charge carriers and stability with respect to reduction is achieved with triarylated Lewis acid units, in particular perarylated borane units. This leads to an improved lifetime of the emission layer which in turn increases the lifetime of the component and eliminates the need for correcting brightness during operation. Furthermore, the invention relates to organic light-emitting diodes in which the position of the emission zone in the emitter layer and the color of the emission can be influenced in a targeted manner through triarylated Lewis acids such as perarylated borane units.

The molecular species are selected such that the resulting modified surface region has critical surface energy between 20 and 30 dynes/cm. In certain embodiments, the covalently coupled molecular species comprise one or more methyl groups. An advantage of the present invention is that novel medical devices are provided, which have a surface with a critical surface energy value that has been shown to display enhanced biocompatibility, including enhanced thromboresistance, relative to other surfaces.

  • Publication number: 20090281264
    Abstract: Disclosed is a method of removing a residual catalyst metal compound from a polymer solution. The method comprises the steps of: a) mixing a solution in which at least one organic nitrogen compound is dissolved in a polar solvent and the polymer solution to precipitate a chelate compound of the organic nitrogen compounds and the residual catalyst metal compound, b) adding the polar solvent to the solution mixture to dissolve a chelate compound and to precipitate a polymer, and c) filtering the precipitated polymer. After the polymer polymerization is completed, an organic nitrogen compound solution is added to perform a chelate reaction with the residual catalyst metal compound in a solution phase, and the polar solvent is added to precipitate the polymer so that only polymer precipitates are filtered while an additional filtration process in respect to the chelate compound is not performed to easily remove the residual catalyst metal compound.

  • Publication number: 20090127547
    Abstract: Pi-conjugated organoboron polymers for use in thin-film organic polymer electronic devices. The polymers contain aromatic and or unsaturated repeat units and boron atoms. Pi-conjugated organoboron polymers which are end capped, derivatized with solubilizing groups or both exhibit improved solubility and handling properties beneficial for the formation of thin films useful for device fabrication. The vacant p-orbital of the boron atoms conjugate with the pi-conjugated orbital system of the aromatic or unsaturated monomer units extending the pi-conjugation length of the polymer across the boron atoms. The pi-conjugated organoboron polymers are electron-deficient and, therefore, exhibit n-type semiconducting properties, photoluminescence, and electroluminescence.
