A ligand of Formula (A):
or a carboxylate salt thereof; wherein Y
1
, Y
2
and Y
3
each independently represents —COOH or a picolinate of Formula (i):
wherein each R
1
independently represents a chromophore group; L
1
, L
2
and L
3
each independently represents a single bond or a linker; and X
1
, X
2
and X
3
each independently represents a hydrogen atom, a coupling function or a bio-vectorizing group. Also, a process for manufacturing the ligand and to a process for manufacturing a chelate by complexation by the ligand of a rare-earth cation, preferably a lanthanide cation. Further, a use of the ligand and/or the chelate in biological imaging and/or photoluminescence imaging.
