Soft Luminescent Materials Based on Ag(I) Coordination Complexes

Abstract

The synthesis and characterization of a new liquid-crystalline columnar 2,2′-bipyridine silver complex containing the 2,2′-bipyridine and benzoate as ancillary ligand, both functionalized with long alkyl chains was performed, along with a full photophysical investigation both in solution and in different condensed states. Furthermore, in order to get more insights about their solid-state architectures, structural studies have been performed on a model complex. The new complexes are luminescence in solution, but on passing to the condensed states, this luminescence is quenched or red-shifted, as a function of different “soft” or “hard” organizations inducted by varying the temperature.
