## 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′

Luminescence Lifetimes of several complex ions at 77% and 4.2'K arc reported. The Lifetimes are shortened in a magnetic field. The results indicate that emission occurs from scvera! states in Boltzmann equilibrium, at least one of which possesses a magnetic moment.
