Abstract
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 EuIII and TbIII 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.
