Nawroth, Martin Uhlemann, Ulrich Stoeck, Lars Giebeler, Rainer Jordan, Alexander Hildebrandt Protocols for anionic polymerization of vinylferrocenes in bulk (b) and solution (s) are reported. Polymerization of vinylferrocenes bearing one or multiple (2–4) vinyl groups yielded linear polyvinylferrocene PVF-1(b, s) or cross-linked polyvinylferrocenes PVF-2 – PVF-4(b, s), respectively. Furthermore, copolymerization of mono-with multifunctional vinylferrocenes produced cross-linked copolymers PVF-5 – PVF-7(b, s). For anionic polymerization in bulk, a high monomer conversion and a relatively high dispersity was observed. A reversible redox behavior of the ferrocenyl group with cycle stability up to 100 cycles was found for PVF-(1s – 7s). Li-ion battery cell tests demonstrated the applicability of the polyvinylferrocenes PVF-1b and PVF-(5b – 7b) as electrode materials. Graphical abstract
