Varying the time between adding a co‐structure‐directing agent and a silica source to an anionic surfactant template results in either well‐ordered cubic or a novel tetragonal ( P 4 2 / mnm ) mesocage material by arrangement of micellar spheres of various sizes. The image shows the high‐resolution transmission electron micrograph of the tetragonal structure and the corresponding electron diffraction pattern (inset).
