Abstract

A phosphorescent metal complex compound, a method for the preparation thereof and a radiation component, in particular an organic light emitting electrochemical cell (OLEEC) use a bidentate ligand containing a triazole unit. Some of the blue emitters shown here for the first time, in particular the class of iridium complex compounds presented here, are the bluest emitters that have ever existed.
