Self‐assembled crystalline porous organic salts (CPOSs) formed by an acid–base combination and with one‐dimensional polar channels containing water molecules have been synthesized. The water content in the channels of the porous salts plays an important role in the proton conduction performance of the materials. The porous salts described in this study feature high proton conductivity at ambient conditions and can reach as high as 2.2×10⁻² S cm⁻¹ at 333 K and under high humid conditions. This is among the best conductivity values reported to date for porous materials, for example, metal–organic frameworks and hydrogen‐bonded organic frameworks. These materials exhibiting permanent porosity represent a group of porous materials and may find interesting applications in proton‐exchange membrane fuel cells.

高质子电导率的结晶性多孔有机盐的合成

已经合成了由酸碱结合形成的自组装晶体多孔有机盐（CPOS），并具有一维极性通道，其中包含水分子。多孔盐通道中的水含量在材料的质子传导性能中起着重要作用。本研究中描述的多孔盐在环境条件下具有高质子传导性，并且可以高达2.2×10 ^-2 S cm ^-1在333 K和高湿度条件下。这是迄今为止报道的多孔材料的最佳电导率值之一，例如，金属有机骨架和氢键有机骨架。这些具有永久孔隙率的材料代表了一组多孔材料，并可能在质子交换膜燃料电池中找到有趣的应用。
