We report the first example of crystallographic observation of acetylene binding to -NO groups in a metal-organic framework (MOF). Functionalization of MFM-102 with -NO groups on phenyl groups leads to a 15% reduction in BET surface area in MFM-102-NO. However, this is coupled to a 28% increase in acetylene adsorption to 192 cm g at 298 K and 1 bar, comparable to other leading porous materials. Neutron diffraction and inelastic scattering experiments reveal the role of -NO groups, in cooperation with open metal sites, in the binding of acetylene in MFM-102-NO.
我们报道了在金属有机框架（MOF）中乙炔与 -NO 基团结合的晶体学观测的首个实例。在苯基上用 -NO 基团对 MFM-102 进行功能化，导致 MFM-102-NO 的 BET 表面积降低了 15%。然而，这与在 298 K 和 1 bar 下乙炔吸附量增加 28%至 192 cm³/g 相关联，这与其他领先的多孔材料相当。中子衍射和非弹性散射实验揭示了 -NO 基团与开放金属位点协同作用在 MFM-102-NO 中乙炔结合过程中的作用。
