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 CDCl(3) switches to vase conformation upon addition of polar solvents such as acetone-d(6) or THF-d(8).
通过间苯二酚杯芳烃穴状配体前体高产率合成了三种新的共价连接分子胶囊。这些胶囊在温度或pH值变化时会在封闭的“花瓶”形式和开放的“风筝”形式之间进行可逆的构象转换。在CDCl(3)中通过任何一种方法获得的风筝构象，在加入极性溶剂如丙酮-d(6)或四氢呋喃-d(8)后会转变为花瓶构象。
