The first organometallic miktoarm star copolymer, PFS(PI)3 (PFS = polyferrocenyldimethylsilane, PI = polyisoprene) with PDI of 1.04 was synthesized through anionic polymerization by using SiCl4 as the coupling agent and its well‐defined structure was characterized by using GPC and 1H NMR spectroscopy. In contrast to analogous diblock copolymers with similar PFS volume fractions which self‐assemble to form cylindrical structures, PFS(PI)3 formed unimolecular micelles in the PI selective solvent, hexane. magnified image
