摘要：

In the presence of methanol the tetrakis(benzoxazines) complex tetramethylammonium cation within the cavity, and the cavity is completely sealed by two intramolecular hydrogen bonds between amide groups. The Cl- anion is found external to the cavity. In CHCl3, Me4N+ is complexed within the cavity, but the Cl- anion acts as a stopper in the upper rim of the cavity, hydrogen-bonded to the amide groups. The solution results are supported by single-crystal X-ray structural studies of both the single-molecule molecular capsules, and those stoppered by Cl-. Copyright © 2002 American Chemical Society.
