[structure: see text]. A series of self-complexing tetrabenzimidazole cavitands have been synthesized. Alkyl chains appended to the rim helically coil into the cavity in competitive organic solvents. These "flexible arms" exchange with each other, a process shown by 2D NMR to proceed via an intermediate solvent-containing species.

苯并咪唑空泡体。在竞争性有机溶剂中,连接到轮缘的烷基链盘绕成螺旋状进入空腔。这些“挠性臂”彼此交换,通过2D NMR显示的过程是通过包含中间溶剂的物质进行的。
