A systematic study of the effectiveness of various chromophores of the 5-aryl-2,2ʹ-bipyridine series was carried out in terms of sensitization of lanthanide(III) cations. For this purpose, the corresponding DTTA-appended 5-aryl-2,2′-bipyridines were synthesized in good yields by using the “1,2,4-triazine” methodology, and their europium(III) and terbium(III) complexes were prepared.
