This article presents a general overview about the designed synthesis of one-dimensional (1-D) inorganic
and organic–inorganic hybrid fibrous nanostructures templated through the use of organogelator-based
supramolecular assemblies. The growing number of structural families and derivatives of low-molecularweight organogelators (LMOGs) already used as templates for materials transcription are first presented,
including a detailed compilation with relevant information about the gelation properties and the
morphologies of their resulting self-assembled fibrillar networks (SAFINs). The main types of
intermolecular interactions responsible for the gel-phase formation and some of the principal variables
governing the gelation process and controlling the obtained fibrous morphologies (fibers, rods, ribbons,
helices, tubes, etc.) are also discussed. After highlighting the most important processing methodologies
that are available for materials transcription through organogel templates (coassembly, post-transcription,
or self-templating procedures), the manuscript presents an updated description of the different inorganic
(silica-based, other metal oxides, nonoxides) and organic–inorganic hybrid fibrous materials so far
templated by using these approaches. The key mechanistic aspects and different templating pathways
involved in the transcription process are also discussed, concluding with a final discussion about challenging
aspects or future prospects in this field. [-]
