Beschreibung
Zusammenfassung:	A light-emitting electrochemical cell comprising at least two electrodes, and an electroluminescent material arranged between said electrodes, wherein said electroluminescent material comprises a charged metal complex is disclosed. The charged metal complex has at least one metal atom selected from the group consisting of Ir, Os, Pt, Re and Zn, with the proviso that said metal complex is different from [Ir(ppy)2(dtb-bpy)](PF6) and [Os(bpy)2(dppe)](PF6)2. The invention also discloses a method of preparing the light-emitting electrochemical cell.
