Abstract:

The interaction between phenol and poly(4-vinylpyprine) was investigated by means of the technique of dipolar filtered fast magic angle spinning(DF-MAS) combined with deuterium dilution 1H NMR. Experiment results reveal that strong hydrogen bond exist between phenol and poly(4-vinlypyridine), which is in good agreement with the data obtained from liquid state 1H NMR. Moreover, the difference in signals of water in MAS NMR disclosed that water was replaced by phenol in the binding with P4VP, and the interaction site between P4VP and phenol was on the H atoms which were near the N atom. Thus, this protocol was proved to be a powerful method for studying adsorption mechanism between insoluble adsorbents and target molecule in situ, which may facilitate the designing for new materials for adsorption and separation.
