Abstract

An efficient synthetic route was developed to tailor bipyridine ligands basing on the palladium catalyzed Sonogashira cross-coupling of 4-bromo-2,2’-bipyridine. Structures of the modified bipyridines were elucidated by NMR and X-Ray diffraction analyses. It was shown that the introduced alkynes are co-planar with the bipyridine core, revealing an efficient effect of the substituent on the electronic properties of the ligand.

Keywords. DSSC, 2,2’-bipyridine, dye sensitizers, palladium-catalyzed, Sonogashira.
