ABSTRACT:
Disclosed are electroluminescent metal complexes with triazoles of the formula (I), where n1 is an integer of 1 to 3, m1 and m2 each are an integer 0, 1 or 2, M1is a metal with an atomic weight of greater than 40, L1is a monodentate ligand or a bidentate ligand, L2is a monodentate ligand, Q2stands for an organic bridging group completing, together with the bonding carbon atoms of the triazole ring, an annellated, carbocyclic or heterocyclic, non-aromatic ring, which optionally may be substituted, Q3represents a group of forming a condensed aromatic, or heteroaromatic ring, which can optionally be substituted, as well as new intermediates for the preparation of these complexes, electronic devices comprising the metal complexes and their use in electronic devices, especially organic light emitting diodes (OLEDs), as oxygen sensitive indicators, as phosphorescent indicators in bioassays, and as catalysts.
