  • Patent number: 8652354
    Abstract: Organic additives are used to improve the lifetimes of organic electronic devices, such as electroluminescent devices fabricated from polymer luminescent ink. These additives include moisture getters, thermally-activated organic/inorganic hybrids, radical scavengers, antioxidants, UV stabilizers, and photoretarders. For water and oxygen scavengers, activation at elevated temperatures or through another activation method is preferred. This allows for the handling of the device materials containing the scavenger under a lower temperature condition in air where higher levels of ambiently-supplied water or oxygen may also be present. The invention also improves operational lifetimes as getters, scavengers and similar acting additives serve to reduce detrimental reactive species that transport into the device, are generated during operation, or become reactive during operation due to the presence of excited states or external stimulation by electrical, optical or other means.

    Abstract: A color conversion film that absorbs light from an organic electroluminescent part emitting blue-green light and converts the light to visible light at a longer wavelength. The color conversion film includes two different dyes. A first dye is a polymer dye with an average molecular weight of 1000 to 1,000,000 that absorbs light incident on the color conversion film and transfers the energy of the light to a second dye. The second dye is a dye that receives the energy from the first dye and emits light. With a multicolor-emitting, organic electroluminescent device including the color conversion film, it is possible to achieve excellent conversion efficiency without increasing the thickness of the color conversion film as in a conventional device using a binder resin. Such an organic electroluminescent device may include as well a pair of electrodes at least one of which is a transparent electrode, and an organic electroluminescent layer sandwiched between the electrodes.

    Abstract: A polyheterosiloxane composition includes (A) a first metal (M1), (B) a second metal (M2), and (C) siloxy units having the formula (R13SiO1/2), (R12SiO2/2), (R1SiO3/2), and/or (S1O4/2). R1 is independently a hydrocarbon or halogenated hydrocarbon group including 1 to 30 carbon atoms. The mole fractions of (A), (B), and (C) relative to each other is of the formula [(M1)]a[(M2)]b[R13SiO1/2]m[R12SiO2/2]d[R1SiO3/2]t[SiO4/2]q, wherein a and b are each independently from 0.001 to 0.9, each of m, d, t, and q are independently from zero to 0.9 so long as m, d, t, and q are not all zero and the sum of a+b+m+d+t+q?1. At least one of (M1) and (M2) is a lanthanide metal. The composition exhibits a quantum yield of at least 0.05% and is formed using a method including reacting (A?) a metal (M3) alkoxide, (B?) an optional hydrolyzable metal (M4) salt, (C?) a silicon-containing material and (D) water.

  • Publication number: 20130284265
    Abstract: This invention is related to novel perylene diester derivatives represented by the general formula (I) or general formula (II) as described herein. The derivatives are useful in various applications, such as luminescent dyes for optical light collection systems, fluorescence-based solar collectors, fluorescence-activated displays, and/or single-molecule spectroscopy. The invention also relates to a luminescent medium, such as a luminescent film, that can significantly enhance the solar harvesting efficiency of thin film CdS/CdTe or CIGS solar cells. The luminescent medium comprises an optically transparent polymer matrix and at least one luminescent dye that comprises a perylene diester derivative. Over 16% of an efficiency enhancement to a CdS/CdTe solar cell and over 12% of an efficiency enhancement to a CIGS solar cell can be achieved.

  • Patent number: 8558450
    Abstract: The present invention provides a color conversion film that can maintain sufficient conversion light intensity without increasing the thickness thereof, and a multicolor light-emitting organic EL device that uses such a film. The color conversion film of the invention includes a polymeric dye material that has a weight-average molecular weight of at least 1,000 but not more than 100,000 and that is composed of a first dye unit and a second dye unit. The first dye unit absorbs light incident on the color conversion film and transfers energy of the absorbed incident light to the second dye unit. The second dye unit receives the energy from the first dye unit and emits light.

  • Publication number: 20130261566
    Abstract: The invention is directed to medical device coatings, such as coated guidewires and catheters, containing a visualization moiety providing color to the coating in ambient or applied light. The coating allows for visual or machine inspection of coating properties such as uniformity of coverage. In some embodiments the coatings include the visualization moiety and an activated UV photogroup, which is used to provide covalent bonding in the coating. The visualization moiety can be in particulate form and entrained in the coating, or can be covalently bonded to the hydrophilic polymer backbone. In other embodiments the visualization moiety includes a stilbene chemical group. Exemplary coatings include a hydrophilic vinyl pyrrolidone polymer, which can provide lubricity to the device surface, along with the colored properties.
