A series of mixed-linker bipyridyl metal–organic framework (MOF)-supported palladium(II) catalysts were used to elucidate the electronic and steric effects of linker substitution on the activity of these catalysts in the context of Suzuki–Miyaura cross-coupling reactions. m-6,6′-Me₂bpy-MOF-PdCl₂ exhibited 110- and 496-fold enhancements in activity compared to nonfunctionalized m-bpy-MOF-PdCl₂ and m-4,4′-Me₂bpy-MOF-PdCl₂, respectively. This result clearly demonstrates that the stereoelectronic properties of metal-binding linker units are critical to the activity of single-site organometallic catalysts in MOFs and highlights the importance of linker engineering in the design and development of efficient MOF catalysts.

接头工程对含Pd（II）-联吡啶配合物的金属有机骨架的催化活性的影响

在铃木-宫浦交叉偶联反应的背景下，使用了一系列混合连接的联吡啶金属-有机骨架（MOF）负载的钯（II）催化剂，阐明了连接基取代对这些催化剂活性的电子和空间影响。。与未官能化的m-bpy-MOF-PdCl ₂和m-4,4'-Me ₂ bpy-MOF-相比，m-6,6'-Me ₂ bpy-MOF-PdCl _2的活性提高了110倍和496倍氯化钯₂，分别。该结果清楚地表明，金属结合连接单元的立体电子性质对于MOF中单中心有机金属催化剂的活性至关重要，并突出了连接器工程在高效MOF催化剂的设计和开发中的重要性。
