Two complementary design strategies, isomorphous ligand replacement and heterocycle doping, have been applied to iteratively enhance the proton conductivity of a metal-organic framework, β-PCMOF2. The resulting materials, PCMOF2/(Pz) and PCMOF2/(Tz) (Pz = 1H-pyrazole, Tz = 1H-1,2,4-triazole), have their proton conduction raised almost 2 orders of magnitude compared to β-PCMOF2. The bulk conductivities of these materials are over 10 S cm at 85 °C and 90% relative humidity (RH), while maintaining the parent MOF structure. A solid state synthetic route for doping 1-D channels is also presented.
两种互补的设计策略，同晶取代和杂环掺杂，已被应用于迭代增强金属-有机骨架β-PCMOF2 的质子导电性。所得材料 PCMOF2/(Pz) 和 PCMOF2/(Tz)（Pz=1H-吡唑，Tz=1H-1,2,4-三唑）与β-PCMOF2 相比，质子传导率提高了近 2 个数量级。这些材料在 85°C 和 90%相对湿度（RH）下的体电导率超过 10 S cm，同时保持母体 MOF 结构。还提出了一种用于掺杂 1-D 通道的固态合成路线。
