β-CD与Triton X-100超分子包络物的研究

Study on Inclusion Complexes of β-Cyclodextrin with Triton X-100

通过荧光光谱法和1HNMR研究了水溶液中β-环糊精(β-CD)与TritonX-100形成的超分子包络物.结果表明,在溶液中β-CD与Triton X-100形成了1∶1二元包络物.25℃时超分子包络物的表观稳定常数为(3.04±0.22)×104L/mol.Triton X-100疏水性端包结在β-CD空腔内.

The inclusion complexation of β-CD with TritonX-100 was studied by fluorescence and ^1H NMR measurements. The experimental results indicate that the stoichiometry is 1：1 for the inclusion complexation. Apparent formation constant was estimated to be （3.04±0.22）×10^4 L/tool. The hydrophobic moiety of Triton X-100 was incorporated into the cavity of β-CD.
