✦ Synopsis

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 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.
