我们提出了一种策略,用于创建具有热稳定性的质子传导的协调框架。模板阳离子通过氢键连接1-D链的配位框架具有动态氢键网络,其中质子在没有水支持的情况下移动。固态核磁共振和X射线研究可视化的质子跳跃机制,并揭示了模板提供的1-D链的桥接,以实现质子传导。该模板还使得质子传导网络能够通过模板与1-D链之间的多重相互作用而保持在190 °C。
We present a strategy for creating coordination frameworks exhibiting proton conduction with thermal stability. The coordination framework, where template cations link 1-D chains via hydrogen bonds, has dynamic hydrogen bond networks where protons move without water support. Solid-state NMR and X-ray studies visualized the proton hopping mechanism, and revealed that the templates provide the bridging of the 1-D chains to attain proton conduction. The templates also enable the proton conductive networks to be maintained at 190 °C through multiple interactions between the templates and the 1-D chains.
