Abstract
Official abstract text for this publication.
The present invention relates to the use of transition metal-carbene complexes, in which the carbene ligand(s) is bonded to the transition metal exclusively via carbene carbon atoms, in organic light-emitting diodes, to organic light-emitting diodes comprising at least one aforementioned transition metal-carbene complex, to a light-emitting layer comprising at least one aforementioned transition metal-carbene complex, to organic light-emitting diodes comprising at least one inventive light-emitting layer, and to devices which comprise at least one inventive organic light-emitting diode.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic light-emitting diode comprising at least one transition metal-carbene complex of formula (I) in which the symbols are each defined as follows: M 1 is a metal atom selected from the group consisting of transition metals of group IIB, IIIB, IVB, VB, VIB, VIIB, VIII of the Periodic Table of the Elements (CAS version) and Cu, in an…
