以间苯二酚芳烃为前体，合成了三种新型共价连接分子胶囊。在温度或pH变化时，胶囊在封闭的“花瓶”形式和开放的“风筝”形式之间进行可逆的构象转换。在加入极性溶剂如丙酮-d 6或THF-d8后，在CDCl 3中通过任一方法获得的风筝构象转变为花瓶构象。
Three new covalently linked molecular capsules were synthesized from their resorcinarene cavitand precursors in good yields. The capsules undergo reversible conformational switching between the closed “vase” form and the open “kite” form upon temperature or pH variation. The kite conformation obtained via either method in CDCl3switches to vase conformation upon addition of polar solvents such as acetone-d6or THF-d8.
