Abstract (en)
[origin: WO2012172271A1] The invention relates to compounds having formula (I), in which: A represents a nitrogen atom or a cycle containing 3 to 6 carbon atoms or an aromatic ring comprising 5 to 10 chain links, said cycle and said aromatic ring optionally comprising one or more heteroatoms chosen from N, O and S; W represents a grafting function; and X and Y represent chelating functions.
