| Abstract: | A novel supramolecular alternating polymer is constructed based on double molecular recognition events of benzo‐21‐crown‐7 with a secondary ammonium salt and of pillar[5]arene with a neutral guest. The resulting polymer is utilized to prepare hierarchical materials with different dimensionalities for the first time. These materials included zero‐dimensional spherical aggregates, one‐dimensional nanofibers, two‐dimensional microstructured films, and three‐dimensional ordered glue. This development will be helpful for designing and preparing supramolecular hierarchical materials with different dimensionalities. |
