Elaborate transcription of unimolecular stacks or helically bundled fibers of sugar‐appended porphyrin gelators into silica by sol–gel polycondensation of tetraethoxysilane gives unique hollow silica fibers with a monodispersed 4‐nm inner diameter (left picture) and huge helical silica bundles (right picture), respectively.
