摘要

以 L-组氨酸为模板，在水热条件下合成了三维（3D）开放框架的亚磷酸铈草酸盐 Ce2(H2O)2(H2PO3)2(C2O4)3-C6H11N3O2-H2O(1)。有趣的是，这是首个以氨基酸为模板的亚磷酸镧-草酸盐化合物。化合物 1 显示出具有 8 环、12 环和 20 环通道的三维框架，并具有莫氏莫干石拓扑结构。1 的通道中存在大量自由水分子和组氨酸阳离子，有利于质子的高效转移。相应地，化合物 1 显示出与温度和湿度相关的质子传导性，在 75 °C 和 98 % 相对湿度条件下的最高值为 3.67 × 10-4 S cm-1。

A 3D open-framework amino acid templated cerium phosphite-oxalate showing proton conductive property

Using L-histidine as template, a three-dimensional (3D) open-framework cerium phosphite-oxalate, Ce₂(H₂O)₂(H₂PO₃)₂(C₂O₄)₃·C₆H₁₁N₃O₂·H₂O (1), has been synthesized under hydrothermal condition. Interestingly, it is the first example of lanthanide phosphite-oxalate with amino acid as the template. Compound 1 shows 3D framework with 8-, 12- and 20-ring channels and has a mog Moganite topology. A large amount of free water molecules and histidine cations are located in the channels of 1, which are favorable to the efficient proton transfer. Correspondingly, compound 1 displays temperature and humidity dependent proton conductivity with the highest value of 3.67 × 10⁻⁴ S cm⁻¹ at 75 °C and 98 % RH.
