In the present work, new host-guest binding motifs based on a water-soluble pillar[6]arene dodecyl-ammonium chloride (CP6) with two aromatic sulfonic acids in aqueous media were fabricated. In accordance with the integrated results of H NMR, 2D NOESY, and florescence titration experiments, it was demonstrated that the host-guest binding of CP6 with the two aromatic sulfonic acids in aqueous solution not only has high binding constants but also has pH-responsiveness.
在本研究中，制备了基于水溶性柱[6]芳烃十二烷基氯化铵（CP6）与两种芳族磺酸在水性介质中的新型主客体结合基序。根据1H NMR、二维NOESY和荧光滴定实验的综合结果，证明CP6与两种芳族磺酸在水溶液中的主客体结合不仅具有高结合常数，而且具有pH响应性。
