Abstract
Disclosed is a salt of an organometallic complex cation and an organometallic complex anion, wherein the cation as well as the anion consists of a central metal atom M of atomic weight greater than 40 associated to 2 or more ligands, at least one ligand comprising a cyclic organic moiety with a carbon atom bonding to M, and at least one ligand comprising a cyclic organic moiety with a nitrogen atom bonding to M. The novel salts may be used as conductive and/or light emitting components in electronic devices. Color emission may be chosen by selecting anion(s) and cation(s) of suitable emission characteristics.
