Preparation and near-infrared optical limiting property of fluorene-containing functional polyacetylene
摘要:
A novel functional polyacetylene containing fluorene group as a pendant, poly (2-(p-methylstyrene)-7-acetylene-9, 9-dioctyl-fluorene), was synthesized in moderate yield by[Rh (nbd)Cl]2-Et3N catalyst. The structures and properties of monomer and polymer were characterized and evaluated with FTIR, NMR, UV-vis, GPC and Z-scan, respectively. The results show that the incorporation of fluorene into polyacetylene has endowed the resultant polymer with well optical limiting properties for laser at wavelength 780 nm based on two-photon absorption mechanism.
