Abstract: The invention relates to a method for increasing the Stokes shift of an emitting metal complex having a given geometry in the region of the metal center in the electronic ground state, wherein said geometry is changing as a result of an optical excitation or an excitation by a hole-electron recombination, and to a polymeric matrix by means of which it is possible to influence the change in geometry in the excited state.

Abstract: The invention relates to a composition comprising an organic emitter molecule, this molecule having a ?E(S1?T1) value between the lowermost excited singlet state (S1) and the triplet state beneath it (T1) of less than 2500 cm?1, and an optically inert atom or molecule for reducing the inter-system crossing time constant of the organic molecule to less than 10?6 s.

Abstract: The invention relates to neutral mononuclear copper (I) complexes for emitting light and with a structure according to formula (A) in which: M represents: Cu(I); L?L represents: a single, negatively charged, bidentate ligand; N?N represents: a diimine ligand (substituted with R and FG), in particular a substituted 2,2?-bipyridine derivative (bpy) or a substituted 1,10-phenanthroline derivative (phen); R represents: at least one sterically demanding substituent for preventing the planarisation of the complex in the excited state; FG=functional group, and represents: at least one second substituent for increasing solubility in organic solvents.

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.

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.

Abstract: The present invention pertains to the double complex salts in optoelectronic components, like organic diodes, organic transistors or organic lasers, in particular an organic solar cell (OSC, OPP) and in particular from oligomers built from charged metal complexes.
