Due to their unique properties, which cannot be realized by polymers with organic structures, polysiloxanes have found many applications. Low glass-transition temperatures, high thermal stability, biocompatibility, hydrophobicity, large gas permeability, oxidative resistance and a low surface energy are among the properties resulting from the polar siloxane backbone. We were interested in combining these features with those of terpyridines, which represent key building blocks in supramolecular chemistry. Introducing such terpyridine moieties and their transition metal complexes into polymeric structures opens the way to novel functional supramolecular materials. In this contribution we present our results on the synthesis of terpyridine-functionalized polydimethylsiloxanes (PDMSs) and their corresponding Fe(II) and Ru(II) complexes via different synthetic pathways.
