  • Publication number: 20130025649
    Abstract: The invention relates to the use of a platinum-dicyano-bisisocyanide complex cluster, having a small ?E distance, in particular between 500 cm?1 and 3000 cm?1, between the lowest triplet state and the overlying singlet state that is populated by means of thermal repopulation from the triplet, in an organic-electronic device for emission of blue light and for absorption in the ultraviolet and blue spectral range. The invention also relates to the use of the singlet harvesting method. Furthermore, the invention relates to the use of the high degrees of absorption of such platinum-dicyano-bisisocyanide complex clusters.

  • Publication number: 20120326103
    Abstract: Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and/or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained.

  • Publication number: 20120184738
    Abstract: The invention relates to copper(I) complexes of the formula (A) with X?Cl, Br or I (independently of one another) N*?E=bidentate ligand, with E=phosphinyl/arsenyl radical of the form R2E (where R=alkyl, aryl, alkoxy, phenoxy, amide); N*=imine function. Which is part of an aromatic group selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl and imidazolyl, the aromatic group optionally having at least one substituent for increasing the solubility of the copper(I) complex in an organic solvent, and “?”=at least one carbon atom, which is likewise part of the aromatic group, the carbon atom being located both directly adjacent to the imine nitrogen atom and to the phosphorus or arsenic atom, and also to the use thereof in optoelectronic assemblies, especially in OLEDs.

  • Publication number: 20110012099
    Abstract: The invention relates to the use of compositions as emitters or absorbers in an electronic component, wherein the compositions have a first neutral transition metal complex and a second neutral transition metal complex. According to the invention, the first transition metal complex and the second transition metal complex together form a column structure. The invention further relates to a method for the production of electronic components having such compositions.

  • Publication number: 20070218023
    Abstract: Melatonin, which can be produced in the skin, exerts a protective effect against damage induced by ultraviolet radiation (UVR). The present study investigated the effect of UVB, the most damaging component of UVR, on melatonin metabolism in HaCaT keratinocytes and in a cell-free system. Four metabolites were identified by HPLC and LC-MS: 6-hydroxymelatonin, AFMK, 2-hydroxymelatonin (the main intermediate between melatonin and AFMK) and 4-hydroxymelatonin. Concentrations of these photoproducts were directly proportional to UVR-dose and to melatonin substrate content, and their accumulation was time dependent. The UVR-dependent increase of AFMK and 2-hydroxymelatonin was also detected in keratinocytes, where it was accompanied by simultaneous consumption of intracellular melatonin. Of note, melatonin and its two major metabolites, 2-hydroxymelatonin and AFMK, were also detected in untreated keratinocytes, neither irradiated nor preincubated with melatonin.
