A polyhedral oligomeric silsesquioxane (POSS)‐based supramolecular amphiphile is prepared from the host–guest inclusion complexation between a mono adamantane‐functionalized POSS (AD‐POSS) and a β‐cyclodextrin oligomer (P(β‐CD)). Assisted by the interface of H 2 O/toluene, the obtained supramolecular hybrids self‐assemble into stable hollow nanospheres with thick walls. These hollow nanospheres aggregate together into a sphere layer through a spin coating technique, which then further transforms into a thin porous film containing nanometer‐scale holes. The hollow nanospheres have a low cytotoxicity. The in vitro cell culture indicates the nanoporous films promote adhesion and proliferation of cells. The self‐assembly morphologies and structures have been carefully characterized by SEM, TEM, AFM, DLS, XPS and water‐contact angle measurements, and the self‐assembly mechanism has also been discussed.
