New 4,4′-oligophenylenevinylene functionalized-[2,2′]-bipyridyl chromophores: synthesis, optical and thermal properties
Résumé
The synthesis and characterization of new bipyridyl-based chromophores featuring extended oligophenylenevinylene π-conjugated backbones are reported. Their absorption and emission properties as well as their thermal stabilities are discussed in comparison to those of the parent ligand.
