Europium complex of 2,2′-bipyridine-6,6′-dicarboxylic acid bis[di(phosphonomethyl)amide] as a new efficient water-soluble luminescent dye

Add time:08/06/2019    Source:sciencedirect.com

A new water-soluble luminescent complex of europium with an organic ligand bearing di(phosphonomethyl)amide moiety has been synthesized and characterized by NMR spectroscopy and HRMS-ESI analysis. Its luminescence quantum yield is 4.7 and 1.2%, and luminescence lifetime is 0.7 and 0.5 m in methanol and water solutions, respectively. This type of complex can be used as biochemical luminescent probe.
