功能性多孔金属有机框架（MOF）已被探索在催化、化学传感、水捕获、气体储存和分离等领域的许多潜在应用。MOF 是解决我们社会面临的与能源和环境相关的挑战的最有前途的候选材料之一，但功能性多孔 MOF 材料的成功实施取决于其稳定性；因此，稳定MOF的合理设计对于功能性多孔MOF的开发具有重要作用。在这篇焦点文章中，我们总结了具有可控孔隙和功能的稳定 MOF 的合理设计和合成方面的进展。网状化学的实施允许对稳定的多孔 MOF 进行合理的自上而下的设计，该 MOF 具有来自预先选择的构建块的目标拓扑网络和孔结构。我们重点介绍了稳定MOFs的网状合成和应用：（1）基于高价金属离子（例如Al ³⁺、Cr ³⁺、Fe ³⁺、Ti ⁴⁺和Zr ⁴⁺）和羧酸盐配体的MOFs；(2)基于低价金属离子(例如Ni ²⁺、Cu ²⁺和Zn ²⁺ )和唑盐连接体的MOF。我们设想合成策略，包括调制合成和合成后修饰，有可能扩展到其他更复杂的系统，如金属膦酸盐骨架材料。

Rational design of stable functional metal–organic frameworks

Functional porous metal–organic frameworks (MOFs) have been explored for a number of potential applications in catalysis, chemical sensing, water capture, gas storage, and separation. MOFs are among the most promising candidates to address challenges facing our society related to energy and environment, but the successful implementation of functional porous MOF materials are contingent on their stability; therefore, the rational design of stable MOFs plays an important role towards the development of functional porous MOFs. In this Focus article, we summarize progress in the rational design and synthesis of stable MOFs with controllable pores and functionalities. The implementation of reticular chemistry allows for the rational top-down design of stable porous MOFs with targeted topological networks and pore structures from the pre-selected building blocks. We highlight the reticular synthesis and applications of stable MOFs: (1) MOFs based on high valent metal ions (e.g., Al³⁺, Cr³⁺, Fe³⁺, Ti⁴⁺ and Zr⁴⁺) and carboxylate ligands; (2) MOFs based on low valent metal ions (e.g., Ni²⁺, Cu²⁺, and Zn²⁺) and azolate linkers. We envision that the synthetic strategies, including modulated synthesis and post-synthetic modification, can potentially be extended to other more complex systems like metal-phosphonate framework materials.
