Abstract

Two structurally analogous self-assembled bowl-shaped hosts were obtained in close to quantitative yields via hydrazone condensation in acidic aqueous media, where the dynamic nature of hydrazone bonds was activated. Each bowl bears nine positive charges, endowing it with good water solubility. The bowls can thus take advantage of the hydrophobic effect and/or electrostatic forces to recognize neutral or anionic guests. Upon being accommodated within the host cavity, an anthracene derivative was protected from UV-stimulated oxidation.

保护客人免受氧化的分子碗
通过在酸性水介质中进行腙缩合,激活腙键的动态性质,获得了两种结构类似的自组装碗状宿主,产量接近定量。每个碗都带有九个正电荷,因而具有良好的水溶性。因此,这些碗可以利用疏水效应和/或静电力来识别中性或阴离子客体。蒽衍生物被容纳在主腔中后,可防止紫外线刺激下的氧化。
