Abstract

We describe the calixarene-cyclodextrin-coupling via click reaction starting from 5,11,17,23-tetra-tert-butyl-25,27-dipropargylether-26,28-hydroxy-calix[4]arene (calix[4]arene-dipropargylether) (2) onto 6I-azido-6I-deoxycyclomaltoheptaose (3) under microwave assisted conditions. The coupling was proven by MALDI-TOF mass spectrometry, ¹H NMR and IR-spectroscopy. The pH dependent supramolecular complex formation with poly(NIPAAM) bearing attached adamantyl units was investigated by dynamic light scattering (DLS) and turbidity measurements.

摘要

我们描述了通过点击反应将杯芳烃-环糊精偶联，起始于 5,11,17,23-四叔丁基-25,27-二炔基醚-26,28-羟基杯[4]芳烃（杯[4]芳烃-二炔基醚）（2）与 6I-叠氮-6I-去氧环麦芽七糖（3）在微波辅助条件下进行。通过 MALDI-TOF 质谱、1H NMR 和 IR 光谱证明了偶联。通过动态光散射（DLS）和浊度测量研究了带有附着的金刚烷基单元的聚（NIPAAM）的 pH 依赖性超分子复合物形成。
