The invention relates to compounds, to the complexes they form with a lanthanide, and to the use of the complexes for fluorescence marking or NMR imaging. The complex consists of an Ln ion and a ligand R&#x2014;C(X&#x2014;R)(R)&#x2014;NRR. Ris a functional group, X is a single bond or a hydrocarbon-based chain consisting of at least one alkylene or alkenylene group optionally comprising at least one hetero atom or an arylene. Ris an anionic group Aor a C-Calkylene or alkenylene group bearing at least one such group Aand optionally comprising at least one hetero atom. Ris H or a C-Calkylene or alkenylene group optionally containing at least one hetero atom, and optionally bearing at least one anionic group A. Ris a substituent with light-absorbing properties that forms chelate rings with Ln. Ris a substituent that forms chelate rings with Ln.
