Abstract
Selective 13C-labelling of carboxylate carbons in the linker molecules of flexible metal-organic frameworks (MOFs) makes solid-state NMR spectroscopy very powerful to investigate solvent-induced local structural changes as demonstrated by 13C and 1H NMR spectroscopy on the pillared layer MOF DUT-8(Ni). Selective identification of polar solvent-node interactions becomes feasible.
摘要
在柔性金属有机框架（MOF）的连接分子中对羧酸盐碳进行选择性¹³C标记，使得固态核磁共振光谱在研究溶剂诱导的局部结构变化方面非常强大，这在柱状层MOF DUT-8（Ni）的¹³C和¹H核磁共振光谱中得到了证明。极性溶剂-节点相互作用的选择性识别变得可行。
