  A series of novel copoly(p-phenylene)s (PPs) containing an alkyl pendant were successfully synthesized via Ni(0)-catalyzed coupling polymerization. Sulfonated copolymers (SPPs) were achieved by postsulfonation from concentrated H2SO4. SPPs showed good solubility in polar aprotic solvents and gave flexible, tough, and transparent free-standing films by solvent casting. The ion exchange capacities (IECs)

  通过Ni（0）催化的偶联聚合成功地合成了一系列新型的含烷基侧基的共聚对苯撑（PPs）。磺化共聚物（的SPP）通过postsulfonation从浓硫酸实现2 SO 4。SPP在极性非质子溶剂中显示出良好的溶解性，并通过溶剂浇铸获得了柔性，坚韧和透明的自支撑膜。膜的离子交换容量（IEC）为2.50至2.65 meq / g。所有SPP膜均显示出与Nafion相似或更高的质子传导率，尤其是在相对湿度较高（> 70％RH）时（SPP-1：0.271 Scm -1，SPP-2：0.284Scm -1，SPP-3：0.212Scm -1，Nafion：0.127Scm -1；在80°C和95％RH下）。它们还表现出可接受的水吸收率，在80°C时，其吸水率为52–56 vol％，尺寸变化很小。SPP膜的气体渗透率远低于Nafion112。因此，这些材料有望用于燃料电池。

  Friedel–Crafts-type acylation of phenyl ether with 2,5-dichlorobenzoic acid could be accomplished in a single step using trifluoroacetic anhydride and phosphoric acid. The method gave a greater yield (78%) than the conventional two-step process (71%) of acid chloride generation followed by aluminum trichloride–mediated acylation.

  Novel poly(tri-sulfonated phenylene)-block-poly(arylene ether sulfone) copolymers (PTSP-b-PAESs) were synthesized by Ni(0)-catalyzed copolymerization of 2,5-dichloro-3′-sulfo-4′-((2,4-disulfo)phenoxy)-benzophenone and chlorobenzophenone-endcapped oligo(arylene ether sulfone). Their physical properties, morphology and polymer electrolyte fuel cell (PEFC) performance were investigated compared to those of poly(mono-sulfonated phenylene)-block-poly(arylene ether sulfone) and the corresponding random copolymers. They had a low ion exchange capacity (IEC) of 1.1–1.2 meq. g−1 and showed very low water uptake and in-plane dimensional change in water. They exhibited a more well-defined microphase-separated structure composed of hydrophilic and hydrophobic domains, where the hydrophilic domains were well-connected to each other to form the channels for proton conduction, than the mono-sulfonated one. This led to the relatively high proton conductivity under low relative humidities. The corresponding random copolymers exhibited a homogeneous morphology and much lower proton conductivity in spite of a high IEC of 2.0–2.1 meq. g−1. Even under the low humidification of 30% RH at 90 °C and 0.2 MPa, they exhibited high PEFC performance and durability; for example, a cell voltage of 0.69 V at a load current density of 0.5 A cm−2 and a maximum output of 0.73 W cm−2, which was comparable to that of the mono-sulfonated one with a much higher IEC of 1.8 meq. g−1 and much higher than those of the corresponding random copolymers. PTSP-b-PAESs have high potential as polymer electrolyte membranes for fuel cell applications.

  新型聚（三磺化苯基）-嵌段-聚（芳基醚砜）共聚物（PTSP-b-PAESs）是通过Ni（0）催化2,5-二氯-3′-磺酸-4′-（（2,4-二磺酸）苯氧基）二苯甲酮和氯代二苯甲酮封端寡聚（芳基醚砜）共聚反应合成的。与聚（单磺化苯基）-嵌段-聚（芳基醚砜）和相应的无规共聚物相比，它们的物理性质、形态和聚合物电解质燃料电池（PEFC）性能得到了研究。它们的离子交换容量（IEC）较低，为1.1-1.2 meq. g-1，吸水率和在水中的平面尺寸变化非常低。与单磺化物相比，它们表现出更明确的微相分离结构，由亲水和疏水域组成，其中亲水域彼此连接良好，形成质子传导通道。这导致在低相对湿度下具有相对较高的质子电导率。相应的无规共聚物表现出均匀的形态，尽管IEC高达2.0-2.1 meq. g-1，但质子电导率却低得多。即使在90°C和0.2 MPa下30% RH的低湿度下，它们
