The rapid generation of nanopatterned surfaces using thin films of the amorphous diblock copolymer poly(styrene‐ b ‐ferrocenylethylmethylsilane) (PS‐ b ‐PFS) is reported. Spontaneous self‐assembly into vertically oriented cylinders of PFS in a PS matrix is observed on a variety of substrates by spin or dip coating, irrespective of the substrate surface polarity. Pyrolysis of the films affords arrays of 20 nm Fe‐containing ceramic nanoparticles, (see Figure, AFM, 4 μm 2 scan area).
