摘要 本文研究了七元瓜环Q[7]与双子型表面活性剂12-2-12在水溶液中发生的相互作用,探讨了瓜环对表面活性剂性能的影响。结果表明:Q[7]和12-2-12可以形成2∶1的配合物;当存在Q[7]时,表面活性剂的临界胶团浓度(cmc)和最低表面张力(γ_(cmc))增大,降低表面张力的效率(pC_(20))和表面压(Π_(cmc))下降,表面活性和发泡能力降低;同时,表面活性剂的饱和吸附量(Г_(max))降低,最小分子横截面积(A_(min))增大,表面活性剂在溶液表面排列更疏松。瓜环对表面活性剂的性能具有重要影响。 Interaction between the cucurbit[7]uril and a Gemini surfactant,alkanediyl-a,ω-bis( dimethylalky1 ammonium bromide,was studied by ~1H NMR spectroscopy and isothermal titrationcalorimetry( ITC). The Q[7] and a Gemini surfactant can form 2 ∶1 host-guest complexe with a high binding constant. While the Q[7]was added into the aqueous surfactant solutions,the values of cmc,γ_(cmc)and A_(min)increased and the values of pC_(20),Π_(cmc)and Г_(max)decreased. The Q[7] plays a key role in the properties of the Gemini surfactant.
