Enhancement of luminescence of europium(III) ions in water by use of synergistic chelation. Part 1. 1:1 and 2:1 complexes

Studies on the formation of complexes of europium(III) ions in water with various sensitizers are reported. The sensitizers utilized are derivatives of 1,10-phenanthroline-2,9-dicarboxylic acid and 2,2′:6′,2″- terpyridlne-6,6″-dicarboxylic acid. Both 1:1 and 2:1 complexes form, the latter being particularly efficient luminescence enhancers.
