| 英文摘要 | The interactions between beta-cyclodextrin (beta-CD) and the equimolar mixture of sodium tetradecyl sulfate (STS) and sodium perfluorooctanoate (SPFO) were studied by H-1 and F-19 NMR. The results showed that beta-CD selectively included SPFO to form 1 : 1 complexes even though the cmc of STS was remarkably smaller than that of SPFO, i.e. STS was more hydrophobic than SPFO. With the further increase of beta-CD concentration, the 1 : 1 beta-CD/STS complexes were then significantly formed until both 2 : 1 complexes of beta-CD/STS and beta-CD/SPFO were formed simultaneously. As a complement of our previous work, it was noted that when the chain length of sodium alkyl sulfates (C-8 similar to C-12) was further increased to C-14, the extent of selectivity of beta-CD to SPFO was further decreased. In other words, SPFO still showed advantage of competition for beta-CD to form inclusion complexes due to its rigidity and the better fit to the cavity of beta-CD, however, the hydrophobicity of STS showed stronger influence on such selectivity than that of C-8 similar to C-12. |
