Abstract
The invention provides an OLED device containing certain alkali metal cluster compounds with mixed ligands, such compounds, and methods of making them. In particular, the cluster compound is a neutrally charged mixed cluster compound comprising first and second subunits with the first subunit comprising an alkali metal salt of a nitrogen containing a heterocyclic ligand bearing a anionic hydroxy group and the second subunit consisting of an organic alkali metal salt different than the first subunit.
Claims25
An OLED device comprising a cathode, an anode, and having therebetween a layer containing a neutrally charged mixed cluster compound comprising first and second subunits with the first subunit comprising an alkali metal salt of a nitrogen containing heterocyclic ligand bearing an anionic hydroxy group and the second subunit comprising an organic alkali metal salt different than the first subunit, wherein the alkali metal cations of both subunits are the same.
A neutrally charged mixed cluster compound comprising first and second subunits with the first subunit comprising an alkali metal salt of a nitrogen containing heterocyclic ligand bearing an anionic hydroxy group and the second subunit comprising an organic alkali metal salt different from the first subunit, wherein the alkali metal cations of both subunits are the same.
