Abstract: The invention relates to platinum complexes and their use in biomedical applications, like in vitro and in vivo imaging and cell staining. The present invention provides new materials and their use as imaging agent. The formation of luminescent aggregates can allow a switch of the emission leading to a dynamic label and on the formation of soft assemblies, which, in some cases, are even more emissive than the isolated corresponding species.

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.
