Rh(I) Catalyzed Polymerization of Propargylated Monosaccharides to Electrospinable Helically Chiral Linear Polyacetylenes and Sorption-Active Porous Polyacetylene Networks

Popis výsledku v původním jazyce

We report the Rh(I)-catalyzed chain-growth polymerizations of propargylated monosaccharides to form pi-conjugated polyacetylene-type products with the monosaccharide substituents attached to the polyacetylene backbone via short methylene spacers. The homopolymerization provides helically chiral linear polyacetylenes of M-w similar to 20,000 soluble in either water (monosaccharide substituents with free -OH groups) or organic solvents (acetylated monosaccharide substituents). The methodology is established for the transformation of prepared chiral polymers into fibers (average diameter similar to 2.7 mu m) taking advantage of the electrospinning technique. Copolymerization of propargylated monosaccharides with 1,3,5-triethynylbenzene cross-linker provides hyper-cross-linked polyacetylene networks with monosaccharide units content up to 46 wt.%, permanent micro/mesoporosity and S-BET area up to 482 m(2) g(-1). The monosaccharide substituents of the networks serve as centers active in reversible isothermal adsorption of water vapor from the air. The achieved H2O capture capacity of 200 mg g(-1) (298 K, RH = 90%) shows monosaccharides as promising (co)building blocks for the construction of porous materials effective in water harvesting from air.
