Synthesis of homopolymers and block copolymers containing metal coordinating ligands are important due to their potential applications in the fields of optics, electronics and photonics. The terpyridine group is a very useful group due to its three nitrogen atoms that act as a tridentate ligand for a variety of transition metal ions. Well-defined polymers are often critical to obtain the desired properties of these materials. Living anionic polymerization offers unsurpassed control over molecular weight and molecular weight distribution. A recently reported general anionic functionalization method was used to create terpyridine end-functionalized polystyrene. This involved a hydrosilation reaction of synthesized 4'-allyloxy-2,2':6',2''-terpyridine with anionically prepared silyl hydride functionalized polystyrene. The product was characterized by thin layer chromatography, 1H NMR, and MALDI-TOF mass spectrometry.
