Semithiobambusurils, which represent a new family of macrocyclic host molecules, have been prepared by a convenient, scalable synthesis. These new cavitands are double functional: they strongly bind a broad variety of anions in their interiors and metal ions at their sulfur-edged portals. The solid-state structure of semithiobambus[4]uril with HgCl2 demonstrates the ability of these compounds to form linear chains of coordination polymers with thiophillic metal ions. The crystal structure of semithiobambus[6]uril with tetraphenylphosphonium bromide exhibits the unique anion-binding properties of the host cavity and the characteristics of the binding site.
半硫代竹节脲，代表了一类新型的大环主体分子，已通过简便、可扩展的合成方法制备出来。这些新型穴状配体具有双重功能：它们在内部能强烈结合多种阴离子，在硫边缘的入口处能结合金属离子。半硫代竹节[4]脲与氯化汞的固态结构证明了这些化合物能够与亲硫金属离子形成配位聚合物的线性链。半硫代竹节[6]脲与四苯基溴化鏻的晶体结构展示了主体空腔独特的阴离子结合特性以及结合位点的特征。
