An iron constitution : Dark superparamagnetic iron oxide nanoparticles are present within the walls of a hexagonal mesoporous aluminosilicate (as shown by the associated bright‐field TEM image). The simple block‐copolymer‐based “one‐pot” self‐assembly approach enables potential applications in magnetic separation and catalyst technologies.
