摘要

以四苯基羧酸乙烯为配体，成功构建并表征了两种新型阴离子镧系金属有机骨架（Me2NH2）[Ln（HTCBPE-F）·（HCOO）·DMF]·4.5DMF·2H2O （Eu-MOF和Dy-MOF）。这两种mof具有多孔结构和水稳定性，具有不配位羧酸基团和二甲基铵阳离子，在98% RH（相对湿度）和90°C下具有高质子电导率（5.35 × 10−2和1.22 × 10−2 S cm−1）。基于结构特征和活化能，提出了质子转移机理。

Two novel lanthanide metal–organic frameworks based on tetraphenylethylene for ultra-high proton conduction†

Two novel isostructural anionic lanthanide metal–organic frameworks, (Me₂NH₂)[Ln(HTCBPE-F)·(HCOO)·DMF]·4.5DMF·2H₂O ( and ), based on tetraphenylethylene carboxylate ligands were successfully constructed and characterized. These two MOFs possess porous structures and water stabilities with uncoordinated carboxylate groups and dimethyl ammonium cations, which allow for high proton conductivities (5.35 × 10⁻² and 1.22 × 10⁻² S cm⁻¹) at 98% RH (relative humidity) and 90 °C. Based on the structural characteristics and activation energy, the proton transfer mechanism is proposed.
