ABSTRACT We report the Rh(I)‐catalyzed chain‐growth polymerizations of propargylated monosaccharides to form π‐conjugated polyacetylene‐type products with monosaccharide substituents attached polyacetylene backbone via short methylene spacers. The homopolymerization provides helically chiral linear polyacetylenes M w ~ 20,000 soluble in either water (monosaccharide free OH groups) or organic solvents (acetylated substituents). methodology is established for transformation prepared polymers into fibers (average diameter ~2.7 μm) taking advantage electrospinning technique. Copolymerization 1,3,5‐triethynylbenzene cross‐linker hyper‐cross‐linked networks units content up 46 wt.%, permanent micro/mesoporosity and S BET area 482 m 2 g −1 . serve as centers active reversible isothermal adsorption vapor from air. achieved H O capture capacity 200 mg (298 K, RH = 90%) shows promising (co)building blocks construction porous materials effective harvesting
