A convenient approach for the fabrication of robust anion exchange membranes designed for electrochemical applications is presented. A triazatriangulenium carbocation (i.e., 4,8,12-tri-ethano-4,8,12-triazatriangulenium tetrafluoroborate) with a pK_R+ above 20 was used as hydroxide anion and negative charge carrier in polysulfone anion exchange membranes. Morphological analysis of these membranes using high resolution scanning electron microscopy (HRSEM) and small angle X-ray scattering (SAXS) confirmed a phase separation casting process resulting in electrolyte exposed cations. It appears that 4,8,12-tri-ethano-4,8,12-triazatriangulenium brings about an extensive carbocation network within the polysulfone matrix, allowing smooth transport of hydroxide anions with low activation energy value (6.56 kJ mol⁻¹), substantial ion conductivity (23.5 mS cm⁻¹ at 90 °C), and good ion exchange capacity (2.44 ± 072 meq/g). The high stability of the triazatriangulenium cation contributes to the retention of 88% of the initial membrane conductivity for the tested period of 35 days at 60 °C in a 3 M KOH solution. This class of unique carbocations serve as a model system for stable charge carriers in alkaline exchange membranes for electrochemicaltio applications.

提出了一种为电化学应用设计的坚固阴离子交换膜的制造方法。pK _R + 大于20的triazatriangulenium碳阳离子（即4,8,12-tri-ethano-4,8,12-triazatriangulenium四氟硼酸盐）被用作聚砜阴离子交换膜中的氢氧根阴离子和负电荷载体。使用高分辨率扫描电子显微镜 (HRSEM) 和小角 X 射线散射 (SAXS) 对这些膜的形态分析证实了相分离浇铸过程导致电解质暴露阳离子。似乎 4,8,12-tri-ethano-4,8,12-triazatriangulenium 在聚砜基质中产生了广泛的碳正离子网络，允许具有低活化能值 (6.56 kJ mol^-1 )、显着的离子电导率（90 °C 时为23.5 mS cm ^-1）和良好的离子交换容量（2.44 ± 072 meq/g）。triazatriangulenium 阳离子的高稳定性有助于在 3 M KOH 溶液中在 60 °C 下在 35 天的测试期间保持 88% 的初始膜电导率。这类独特的碳正离子用作碱性交换膜中稳定电荷载流子的模型系统，用于电化学应用。
