Abstract
A bowl-shaped organic host was prepared by linking two anthracene-embedded bispyridine ligands with two methylene spacers. The water-soluble host has a hemispherical hydrophobic cavity (∼1 nm in diameter) with two cationic methylenebispyridinyl (Lewis acidic) moieties and shows the selective recognition and encapsulation of aromatic guest molecules containing carbonyl groups in water.
摘要
通过将两个蒽嵌入的双吡啶配体与两个亚甲基间隔物连接，制备了一个碗状有机主体。该水溶性主体具有一个具有两个阳离子亚甲基双吡啶基（路易斯酸性）部分的半圆形疏水性空腔（直径约为 1nm），并在水中对含有羰基的芳香客体分子表现出选择性识别和包合。
