Polyferrocenylsilane microspheres are readily formed under mild reaction conditions. Chemical oxidation leads to positively charged particles that undergo electrostatic self‐assembly with smaller negatively charged silica microspheres, which leads to composite superstructures (see Figure), whereas pyrolysis leads to spherical magnetic ceramics that self‐organize into two‐dimensional arrays in a magnetic field.
