Using the concept of isomorphous replacement applied to entire ligands, a C(3)-symmetric trisulfonate ligand was substituted with a C(3)-symmetric tris(hydrogen phosphonate) ligand in a proton conducting metal-organic framework (MOF). The resulting material, PCMOF2½, has its proton conduction raised 1.5 orders of magnitude compared to the parent material, to 2.1 × 10(-2) S cm(-1) at 90% relative humidity and 85 °C, while maintaining the parent MOF structure.
采用同晶置换的概念应用于整个配体，在质子传导金属有机骨架（MOF）中，用 C(3)-对称的三（氢膦酸）配体取代 C(3)-对称的三磺酸盐配体。得到的材料 PCMOF2½ 与母体材料相比，质子传导提高了 1.5 个数量级，在 90%相对湿度和 85°C 时达到 2.1×10(-2) S cm(-1)，同时保持母体 MOF 结构。
