Abstract

Supramol. chem. has evolved to one of the most active area of research in modern chem. with the design and prepn. of new functional ligands and their incorporation into supramol. assemblies marking the key challenges in this field. Bringing together the chem. of terpyridines, as well as their transition metal complexes, and of pi-conjugated oligomers, we here present the synthesis of a diverse library of rigid pi-conjugated terpyridines. Highly effective combinations of well-known condensation reactions and modern transition metal-catalyzed coupling reactions enable us to synthesize tailor-made terpyridine-derivs. with respect to their photophys. properties. We also introduce the synthesis of oligomer-modified materials with improved processability and good film-formation behavior. The Sn(II)-catalyzed ring-opening polymn. of cyclic esters has been used as a versatile tool to realize these structures. The optical properties of all materials have been studied in soln. and in thin films. Addnl., we show examples for the complexation of the
