  p-Phenylene sulfide oligomers and their properties. Ar–S couplings mediated by copper or by fluorine substitutions

  摘要：

  A series of monodisperse p-phenylene sulfide oligomers were efficiently synthesized by using a bidirectional growth. A strategy combining Cu-catalyzed Ar-S couplings for small oligomers and fluorine aromatic substitutions by aryl thiolates for longer ones was put forward. The latter method is Superior to Cu-catalyzed reactions for longer oligomers. Fluorine chemistry brings some new advantages Such as solubility and reactivity, Qualitative crystallinity studies were reported according to the oligomer size and the functional series, by using a microscope equipped with a heating stage and a camera.

  The invention provides a selenium-containing polyimide polymer, preparation method and use thereof. The method comprises: (1) polymerizing a selenide diamine monomer with a dianhydride monomer to give a selenium-containing polyamic acid; and (2) performing thermal imidization on the selenium-containing polyamic acid obtained in the step (1) to give a selenium-containing polyimide polymer. In the invention, selenium is introduced into polyimides for increasing refractive index to 1.7-1.82, this greatly improves the defects of low refractive index of the existing polyimide materials, thereby expanding its applications in the optics field.

  本发明提供了一种含硒聚酰亚胺聚合物及其制备方法和用途。该方法包括：（1）将硒化二胺单体与二酐单体聚合，得到含硒聚酰胺酸；（2）对步骤（1）中得到的含硒聚酰胺酸进行热酰亚胺化，得到含硒聚酰亚胺聚合物。本发明将硒引入聚酰亚胺中，使折射率提高到 1.7-1.82，大大改善了现有聚酰亚胺材料折射率低的缺陷，从而拓展了其在光学领域的应用。
