Polystyrene-block-polyferrocenylsilane (PS-b-PFS) diblock copolymers were stoichiometrically oxidized in solution using salts of the one-electron oxidant tris(4-bromophenyl)ammoniumyl. Due to a redox-induced polarity change for the PFS block, self-assembly into well-defined spherical micelles occurs. The micelles are composed of a core of partially oxidized PFS segments and a corona of PS. When the micellar solutions were treated with the reducing agent decamethylcobaltocene, the spherical micelles disassemble and regenerate unassociated and pristine PS-b-PFS free chains.
聚苯乙烯-嵌段-聚二茂铁基硅烷（PS-b-PFS）二嵌段共聚物在溶液中使用单电子氧化剂三（4-溴苯基）铵盐进行化学计量氧化。由于PFS嵌段的氧化还原诱导极性变化，会自组装成明确的球形胶束。这些胶束由部分氧化的PFS链段的核和PS的冠层组成。当胶束溶液用还原剂十甲基钴茂处理时，球形胶束会解体并再生出未缔合的原始PS-b-PFS自由链。
