Chiral metal–organic frameworks (CMOFs) have emerged as an important subclass of chiral materials; however, their development is hindered substantially by limited enantiopure functional linkers and poor chemical stabilities. Here we report the design and synthesis of a total of five enantiopure spiro-based tetracarboxylate linkers with diverse functionalities and their use in connecting Zr₆ clusters to form an array of highly robust and porous CMOFs. X-ray crystallographic analysis and structure examination unambiguously revealed that the resulting CMOFs possess multifarious three-dimensional networks with novel topologies and pore systems, highlighting the great potential of chiral spiro skeletons in the fabrication of intriguing structures. PXRD and N₂ adsorption experiments validated their exceptional chemical stability towards boiling water as well as aqueous acid and base solutions. Moreover, their potential applications in enantioselective catalysis and separation are also presented.

由螺骨架构建的手性和坚固的 Zr(IV) 基金属有机框架

手性金属有机框架（CMOF）已成为手性材料的重要子类。然而，它们的发展受到有限的对映纯功能接头和较差的化学稳定性的严重阻碍。在这里，我们报告了总共五种具有不同功能的对映纯螺基四羧酸酯接头的设计和合成，以及它们在连接 Zr ₆簇以形成一系列高度稳健和多孔的 CMOF 中的用途。X 射线晶体学分析和结构检查清楚地表明，由此产生的 CMOF 具有多种三维网络，具有新颖的拓扑结构和孔系统，突出了手性螺骨架在制造有趣结构中的巨大潜力。PXRD和N ₂吸附实验验证了它们对沸水以及酸碱水溶液的出色化学稳定性。此外，还介绍了它们在对映选择性催化和分离中的潜在应用。
