A method of synthesis of oligomeric siloxane protic ionic liquids capable of condensation reactions has been developed as starting compounds in the obtaining proton exchange membranes for fuel cells. Their organic frame is characterized by a combination of amine centers of different basicity (aliphatic and imidazole types) neutralized with ethanesulfonic acid and secondary hydroxyl groups. A change in the degree of neutralization of the amine centers significantly affects the structure of the compounds and the mechanism of proton migration. The conductivity of the obtained compounds reaches 9.8·10^–4 S/cm at 100°C in the absence of moisture.

有机框架中具有两种离子位点的质子低聚倍半硅氧烷双离子液体

已经开发了一种合成能够进行缩合反应的低聚硅氧烷质子离子液体的方法，作为获得燃料电池质子交换膜的起始化合物。它们的有机框架的特征在于用乙磺酸和仲羟基中和的不同碱度（脂肪族和咪唑类型）的胺中心的组合。胺中心中和程度的变化显着影响化合物的结构和质子迁移的机制。所得化合物的电导率在 100°C 无水分条件下达到 9.8·10 ^{–4 S/cm。}
