Polystyrene‐block‐poly(4‐vinylpyridine) with nominally one pentadecylphenol molecule hydrogen‐bonded to each pyridine group has been electrospun, leading to fibers with a hierarchical, structure‐within‐structure morphology (see Figure). An internal structure on the nanometer length scale exists within a structure on the tens‐of‐nanometers length scale. Internal porosity can be obtained by selective removal of the amphiphile.
