    • Embodiments described herein relate to compositions including iptycene-based structures. Some embodiments provide compositions including polymers having a backbone comprising an iptycene-based compound. Some embodiments described herein provide compositions having enhanced properties such as enhanced porosity, increased glass transition temperatures, and/or improved solubility as compared to traditional poly(aryl ether)-based compounds or traditional iptycene-based compounds. In some cases, the compositions may include various aryl ether compounds such as an aryl ether ketone incorporated into the polymer backbone. Non-limiting examples of suitable aryl ether compounds include polyaylethersulfones, polyaryletherketones, polyetherimides, and polyphenylene ethers. The compositions described herein may be useful in a wide variety of applications, including structural materials, flexible composites, ion conductors, fuel cell membranes such as proton exchanging membranes, sensors, preconcentrators, absorbents, or the like.
    • 本文所述的实施方案涉及包含基于iptycene的结构的组合物。 一些实施方案提供包含聚合物的组合物,所述聚合物具有包含基于iptycene的化合物的主链。 本文所述的一些实施方案提供具有增强性能的组合物,例如与传统的基于聚(芳基醚)的化合物或传统的基于iptycene的化合物相比,增强的孔隙率,增加的玻璃化转变温度和/或改善的溶解度。 在一些情况下,组合物可以包括各种芳基醚化合物,例如并入聚合物主链中的芳基醚酮。 合适的芳基醚化合物的非限制性实例包括聚醚醚砜,聚芳醚酮,聚醚酰亚胺和聚苯醚。 本文描述的组合物可用于各种应用,包括结构材料,柔性复合材料,离子导体,燃料电池膜,例如质子交换膜,传感器,预浓缩器,吸收剂等。
