Abstract:
The present invention relates to metal-carbene complexes of the general formula (I), where variable M is Ir or Pt and that are characterized by variable R being a group of formula (a). The complexes are used in organic electronic devices, especially OLEDs (Organic Light-Emitting Diodes), illuminating elements, stationary visual display units and in material layers as emitter, charge transport material and/or charge or exiton blocker.
Abstract:
A cyclometallated Ir complex comprising one, two or three ligands of formula (I) or (I′) substituted at the R5 and R7 position; an organic electronic device comprising at least one inventive cyclometallated Ir complex; a light-emitting layer comprising at least one inventive cy-clometallated Ir complex; the use of the inventive cyclometallated Ir complex in an OLED; an apparatus selected from the group consisting of stationary visual display units, mobile visual display units, illumination units, units in items of clothing, units in handbags, units in accessories, units in furniture and units in wallpaper, comprising the organic electronic device; and a process for preparing a the inventive cyclometallated Ir complex.
Abstract:
The present invention relates to the use of a compound of formula I: in dye-sensitized solar cells. It also relates to a compound of formula I′: to a compound of formula I″: to the use of a compound of formula II: as a precursor compound for manufacturing the compound of formula I when q is 0 or 1 and as a precursor compound for manufacturing the compound of formula I′ when q is 1; to a compound of formula III: to the use of the compounds of formulae I, I′ or I″ as sensitizers in dye-sensitized solar cells; and to such dye-sensitized solar cells.
