Self-assembly of borane end-functionalized polystyrene through tris(1-pyrazolyl)borate (Tp) iron(II) linkages.
Treatment of trimethylsilane-terminated polystyrenes with BBr(3)  resulted in the formation of dibromoboryl-functionalized mono- or ditelechelic styrene polymers. Subsequently, the borane moieties were selectively converted to tris(1-pyrazolyl)borate (Tp) moieties capable of transition metal coordination. These novel telechelic polymers assemble into redox-active supramolecular polymer structures upon reaction with Fe(II) as indicated by GPC, UV-vis, and cyclic voltammetry studies.
