Solid-state NMR study of dynamics of molecules in an nanospace

多孔材料内部具有纳米尺寸的孔，具有吸附、分离、催化等功能。纳米空间内表面的性质与这些功能密切相关。在本研究中，我们已经测量了固态NMR光谱的探针分子与内表面相互作用后，将分子引入到纳米空间，以揭示内表面性质的纳米空间。我们选择三甲基氧化膦作为探针分子。我们得到的NMR光谱反映了内表面的酸性质，因为所选的分子具有碱性。

Porous materials with nanometer-sized pores inside have functions such as adsorption, separation and catalysis. The properties of the inner surface of the nanospace are closely correlated with those functions. In the present study, we have measured solid-state NMR spectra of probe molecules interacting with the inner surface after introducing the molecules into the nanospace in order to reveal the inner-surface properties of the nanospace. We selected trimethylphosphine oxide as a probe molecule. We obtained NMR spectra reflecting the acid properties of the inner surface because the selected molecule has a basic property.
