A highly ordered self-assembly three-grade porous helical silica tube.
A novel three-grade porous helical silica tube is prepared through an ingenious multi-soft-template pathway. This study reveals that three-(or multi-)grade self-assembly porous structure can be realized by using the synergistic effect of soft-templates. Our finding can offer an opportunity for nanofabrication including rational molecular design, spatial control on a nanoscale, and hierarchical assembly of complex architectures of porous materials.
