Abstract

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.
