Rigid π-Conjugated Mono-, Bis-, and Tris(2,2‘:6‘,2‘ ‘-terpyridines)

A set of rigid, π-conjugated linear mono- and bisterpyridines and star-shaped tristerpyridines have been synthesized using Pd(0)-catalyzed coupling reactions and the Horner−Wadsworth−Emmons reaction. The terpyridyl ligands obtained feature strong emission in the blue range with high quantum yields i...

Description
Summary:A set of rigid, π-conjugated linear mono- and bisterpyridines and star-shaped tristerpyridines have been synthesized using Pd(0)-catalyzed coupling reactions and the Horner−Wadsworth−Emmons reaction. The terpyridyl ligands obtained feature strong emission in the blue range with high quantum yields in dilute solution and thin films.
