<p>The present invention relates to an organometallic complex, to the preparation of said material, to the use of said material and to a light emitting device which transform electric energy into light. The present invention is further related to provide phosphorescent complexes which contribute to extend the life time in operation of said OLEDs and especially when they are involved in the EL. The objectives of this invention are accomplished by iridium complex comprising 7-membered fused ring ligands which are tris-homoleptic or bis-homoleptic with an ancillary ligand.</p>
