52. Influence of Chelating Groups on the Luminescence Properties of Europium(III) and Terbium(III) Chelates in the 2,2'-Bipyridine Series

Article abstract of DOI:10.1002/hlca.19930760213

Eight different 2,2'-bipyridine derivatives, i.e. 2, 5, 8, 10, 12, 13, 15, and 19 (Schemes 1 and 2), were prepared to study the influence of the chelating groups on the luminescence properties of their Eu^III and Tb^III chelates.According to our luminescence results, 2,2'-(methylenenitrilo)bis(acetic acid) as well as (methylenenitrilo)bis(methylphosphonic acid) in 6- and 6'-position of 2,2'-bipyridine is a suitable group when developing luminescent markers for bioaffinity assays based on time-resolved luminescence measurement.
