SYNTHESIS,HELICITY,AND BIOLOGICAL PROPERTIES OF MONOSACCHARIDE-CONTAININGPOLY(PHENYLACETYLENE)S

摘要

Poly(phenylacetylene)s bearing monosaccharide pendant groups are synthesized in high yields by [Rh(nbd)Cl]2 catalyst. The polymers have high molecular weights and give satisfactory spectroscopic data corresponding to their molecular structures. They are thermally quite stable (≥300℃) and show strong circular dichroism signals in the visible spectral region owing to the helicity of the polyene backbone. The monosaccharide-containing polyacetylenes are cytophilic and can stimulate the growth of living cells.
