This review covers basic design principles and offers a cross-section of the current status of phosphonate MOFs as proton conductors. Metal phosphonates are often sustained by strong bonds that render them very stable materials. The phosphonate group can also coordinate as a protonated species. These factors, coupled with the inherent structural versatility intrinsic to any metal organic framework family, are the foundation of their interest as proton conducting materials. This review summarizes the recent progress in this topical field as well as some of the existing challenges for further development. The present state of application of the materials is still largely in the academic domain but increasingly, new structures with the necessary proton conducting ability and stability to merit further development as membranes are being reported. The review concludes with a discussion of future challenges for development of this promising field.

这篇综述涵盖了基本的设计原理，并提供了有关膦酸酯MOF作为质子导体的当前状况的剖视图。金属膦酸盐通常通过牢固的键保持，这使它们成为非常稳定的材料。膦酸酯基团也可以作为质子化的基团进行配位。这些因素，再加上任何金属有机骨架家族固有的固有结构通用性，是它们作为质子传导材料的兴趣的基础。这篇综述总结了该主题领域的最新进展以及未来发展中的一些现有挑战。材料的当前应用状态仍然主要在学术领域，但是越来越多地，随着膜的报道，具有必要的质子传导能力和稳定性的新结构值得进一步发展。
