We studied the relationship between proton conductivity and the terahertz-regime vibrations of two-dimensional MOFs. The results of spectroscopy studies clarified the essential role played by the collective motions in the terahertz region in 2D layers for efficient H⁺ conduction. Ab initio calculations suggested the collective motion to be predominantly determined by the valence electronic structure, depending on the identity of the metal ion.

太赫兹区域中晶格振动在二维金属-有机框架中质子传导中的作用

我们研究了质子电导率与二维MOF的太赫兹状态振动之间的关系。光谱学研究的结果阐明了2D层太赫兹区域中集体运动对于有效H ⁺传导所起的重要作用。从头算计算表明，集体运动主要由价电子结构决定，取决于金属离子的身份。
