合成了以咪唑为质子溶剂，通过柔性间隔基连接到聚硅氧烷骨架上的本征质子导电聚合物。除了标准的表征外，还研究了它们的热性能和传输行为。由于咪唑基团的自解离和由此产生的缺陷的“结构扩散”，该材料表现出质子导电性。特别是，观察到的质子电导率不需要水或单体咪唑等液体。
Intrinsically proton conducting polymers with imidazole as proton solvent tethered to a polysiloxane backbone via a flexible spacer have been synthesized. Apart from the standard characterization also their thermal properties and transport behavior have been investigated. The materials exhibit proton conductivity as a consequence of self‐dissociation of the imidazole moieties and “structure diffusion” of the resulting defects. In particular, no liquid phase such as water or monomeric imidazole is needed for the observed proton conductivities.
