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, PCMOF21/2(Pz) and PCMOF21/2(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 10-1 S cm-1 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.

通过迭代设计进展在金属有机框架中实现超质子传导

两种互补的设计策略，同晶配体置换和杂环掺杂，已被应用于迭代增强金属有机骨架 β-PCMOF2 的质子传导性。所得材料 PCMOF21/2(Pz) 和 PCMOF21/2(Tz)（Pz = 1H-吡唑，Tz = 1H-1,2,4-三唑）的质子传导与 β 相比提高了近 2 个数量级-PCMOF2。这些材料的体积电导率在 85 °C 和 90% 相对湿度 (RH) 下超过 10-1 S cm-1，同时保持母体 MOF 结构。还介绍了掺杂一维通道的固态合成路线。
