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.

嵌入固有微孔聚合物中的钯催化剂用于铃木-宫浦偶联反应†



固有微孔聚合物(PIM)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分步聚合,即活性氟取代的芳环单体和酚类单体。在此,我们报道了一种使用自合成氟化单体和常用单体5,5',6,6'-四羟基-3,3,3',3'-四甲基螺二茚满制备PIMs的新方法。通过四氟邻苯二甲酸酐与芳香二胺的酰亚胺化反应合成含氟单体。所得的 PIM 作为钯的载体,形成的催化剂显示出在铃木-宫浦偶联反应中的应用潜力。
