International audience; Three lanthanide complexes (Ln=Gd, Eu) based on a DO3 A ([Ln(L$_1$)]) or DO2 A ([Ln(L$_{2-3}$)]$^+$) platform appended by a redox active TEMPO-based arm were prepared. Complex [Ln(L$_2$)]$^+$) shows an alkyne arm, offering the

International audience; The DOTA-based ligand H3L (5) appended with a pro-nitroxide moiety has been synthesized. The europium and ytterbium complexes 5Ln show metal-centred luminescence. They react with ROS in aqueous media to give a transient iminon
