Abstract
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) complexes were investigated in aqueous solutions. In the two systems, the 2,2 ′-bipyridine chromophores act as antenna for the sensitization of the lanthanide ion and are not coordinated to the metal. It is shown that the change in ligand structure from 1 to 2 creates a higher antenna-to-metal energy transfer, and consequently a better luminescence quantum yield.
