Sensitization of europium(III) luminescence in bis(bipyridine) DTPA and DTTA-based ligands: effect of the deletion of amide groups

Autor: Jean-Marc Couchet, Claude Picard, Joëlle Azéma, Pierre Tisnès

Publikováno v: Inorganic Chemistry Communications. 6:978-981

Two new ligands containing two 2,2 ′ -bipyridine groups and derived from diethylenetriaminepentaacetic acid (DTPA) ( 1 ) or diethylenetriaminetriacetic acid (DTTA) ( 2 ) were synthesized and the luminescent properties of their europium(III) complex

Publikováno v: Tetrahedron Letters. 44:4869-4872

The convenient synthesis of a new macrocyclic octadentate chelate based on 2,2′-bipyridine chromophore and diethylenetriaminetriacetic acid core is described. In aqueous solutions, the corresponding Eu(III) and Tb(III) neutral complexes are kinetic

Publikováno v: Tetrahedron Letters. 42:6275-6278

A very convenient synthesis of an 18-membered triaza-macrocyclic ligand bearing one endocyclic terpyridine unit and three acetate pendant groups is reported. This nonadentate ligand forms very stable neutral lanthanide complexes in aqueous solution a

Direct access to terpyridine-containing polyazamacrocycles as photosensitizing ligands for Eu(III) luminescence in aqueous media

Autor: Claude Picard, Pierre Tisnès, Sébastien Bedel, Chantal Galaup, Jean-Marc Couchet

Publikováno v: The Journal of organic chemistry. 70(6)

[reaction: see text] The synthesis of new 18-membered hexaazamacrocycles containing a functionalized 2,2':6',2' '-terpyridine moiety as part of the cyclic backbone and three acetate pendant arms is described. The reported synthetic procedure is based
