As a typical planar 4-connected ligand that possesses D_4h symmetry, the squarate ligand is expected to construct some interesting topologies. Here, we report that the assembly of the squarate ligand with rare-earth ions can produce a series of (4, 8)-connected frameworks with the “smallest” scu type topology. Among these compounds, the Tb based analogue not only possesses a good proton conductivity, but also exhibits luminescence responses toward MnO₄⁻ and Cr₂O₇²⁻, making it a candidate for multifunctional materials.

具有 scu 拓扑结构的稀土方形框架

作为典型的具有D _4h对称性的平面四联配体，方形配体有望构建一些有趣的拓扑结构。在这里，我们报告了方形配体与稀土离子的组装可以产生一系列具有“最小” scu型拓扑结构的 (4, 8)-连接框架。在这些化合物中，基于Tb的类似物不仅具有良好的质子传导性，而且还表现出对MnO ₄^-和Cr ₂ O ₇^2-的发光响应，使其成为多功能材料的候选者。
