随着激光设备的不断发展,自动化程度的不断提高,它对人眼及各种电子装置的干扰、损伤等的威胁也越来越大,激光防护越来越受到各国的重视。报道了激光防护共轭功能高分子的分子设计,合成系列共轭高分子,采用FT-IR、^1H NMR、UV、GPC和TGA对分子结构和热性能进行表征,测试了高分子的光限幅和非线性光学性能,讨论了高分子材料热性能增强与光限幅产生的机理以及分子结构与高分子光学性能之间的关系。
Four series Of soluble functional polyacetylene containing stilbene pendant were designed and synthesized. Their structures were characterized by FT-IR, IH NMR, UV, GPC, TGA, and their nonlinear optical properties and optical limiting properties were evaluated using z-scan technique at 532nm wavelength with 8ns pulse width. The relation between molecular structure and optical properties was investigated and discussed.
