Abstract
Integrating the formation of conjugated polymer networks with the construction of macroscopic porous materials remains an important challenge. In this study, monomers containing multiple acetyl and aldehyde groups were polymerized through a metal-free Chichibabin-type condensation. The reaction produced a fully conjugated pyridinic network that simultaneously organized into uniform hollow fibers with submicron dimensions. Entanglement of the resulting fibers generated compressible, sponge-like monoliths in a single reaction step without templates, metal catalysts, or post-treatment. The fibrous and porous structure, together with the conjugated backbone, provided efficient light absorption, a large surface area, and favorable mass transport. These characteristics enabled the monoliths to absorb a variety of oils, photocatalytically decolorize dyes, capture iodine vapor, and provide thermal insulation. The results demonstrate a direct method for preparing conjugated hollow-fiber monoliths and their potential as multifunctional materials for environmental and energy-related applications.
