Abstract:
The invention relates to complexing agents of formula (I) in which A 1 , A 2 , A 3  and R 1  are as defined in the description. The invention also relates to lanthanide complexes obtained from said complexing agents. The invention can be used for marking biological molecules.

Claim (Index 1):
A complexing agent of formula (I): wherein:\n the R 1  groups are identical and are either: \u2014CO 2 H, or \u2014PO(OH)R, wherein R is selected from the group consisting of: phenyl optionally substituted by an \u2014SO 3 H group benzyl, methyl, ethyl, propyl, n-butyl, sec-butyl, isobutyl, and tert-butyl; \n the A 1 , A 2  groups are identical or different and are selected from the group consisting of: a group of formula -L 1 -E; a group of formula (II) and a group of formula (II\u2032); \n the A 3  group is selected from the group consisting of: a group of formula \u2014O-L 3 -G, a group of formula (II), a group of formula (II\u2032), a group of formula and a group of formula (III\u2032); \n L 1 , L 2  and L 3  are identical or different and each represent a divalent linkage group; E is a group that renders the complexing agent water-soluble, chosen selected from the group consisting of: \u2014SO 3 H, \u2014PO(OH) 2 , \u2014CO 2 H, \u2014N + Alk 1 Alk 2 Alk 3 , a carbohydrate residue, a sulfobetaine; and a PEG group; G is a reactive group; Alk 1 , Alk 2 , Alk 3 , which may be identical or different, each represent a (C 1 -C 6 )alkyl.
