  • LANTHANIDE COMPLEXES COMPRISING DENDRIMERS
    Publication number: 20190352511
    Abstract: The present invention relates to a complex comprising at least one dendrimer and at least one lanthanide, wherein the dendrimer comprises a unit of formula (I) below: in which: C1 is a valence group 4 of formula >N—CH2—CH2—N<; A1, A2 and A3 are groups of formula —(CH2)2—C(O)—NH—(CH2)2—; the unit of formula (I) being connected covalently to at least one antenna which absorbs at a wavelength ranging from 500 nm to 900 nm.

  • Lanthanide complexes comprising at least two betaine groups, which can be used as luminescent markers
    Patent number: 10047106
    Abstract: The present invention relates to luminescent lanthanide complexes including a chelating agent, formed with a macrocycle or a set of ligands, complexing a lanthanide ion Ln3+, wherein the chelating agent is substituted with at least two groups. The invention is most particularly applied to lanthanide complexes, the chelating agent of which is formed the with three ligands integrating a 2,6 pyridine-di(carboxylic acid) or is formed with a macrocycle having a 1,4,7 triazacyclononane structure.
