Polymers of intrinsic microporosity (PIMs) are porous polymers with rigid ladder-type chain structures. Synthesizing these polymers usually involves the step polymerization of two types of monomer, namely, active fluorine-substituted aromatic ring monomers and phenolic monomers. Herein, we report a new PIMs preparation method using self-synthesized fluorinated monomers and common monomer 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl spirobisindane. The fluorinated monomers were synthesized through the imidization of tetrafluorophthalic anhydride and aromatic diamines. The resulting PIMs served as a support for palladium, with the formed catalyst showing potential for application in the Suzuki-Miyaura coupling reaction.
固有微孔聚合物（PIMs）是具有刚性梯型链结构的多孔聚合物。合成这些聚合物通常涉及两种单体的逐步聚合，即活性氟取代芳环单体和酚类单体。在此，我们报道了一种使用自合成的氟化单体和常见单体5,5',6,6'-四羟基-3,3,3',3'-四甲基螺双茚满制备PIMs的新方法。氟化单体通过四氟邻苯二甲酸酐与芳族二胺的酰亚胺化反应合成。所得的PIMs用作钯的载体，所形成的催化剂在铃木-宫浦偶联反应中显示出应用潜力。
