The self-assembly of functional structures into metallo-supramolecular architectures through the interaction of transition metal ions and appropriate ligands is a highly active area in modern supramolecular chemistry. Bringing together the chemistry of terpyridines, as well as their transition metal complexes, and of p-conjugated polymers, we here present the synthesis of a diverse library of rigid p-conjugated oligo(terpyridine)s. Highly effective combinations of well-known condensation reactions and modern transition metal-catalyzed coupling reactions enable us to synthesize tailor-made terpyridine-derivatives with respect to their photophysical properties. The electro-optical properties of all materials have been studied in solution and in the solid state. Additionally, we show examples for the complexation of the p-conjugated oligo(terpyridine)s with various transition metal ions leading to various types of supramolecular assemblies (e.g. ABA-block copolymers, chain-extended polymers and PPE/PPV-type oligomers) and potential applications in the fields of photovoltaics or organic light-emitting devices. |
