Cobalt(iii) tetrahedral capsules have been prepared using an assembly-followed-by-oxidation protocol from a cobalt(ii) precursor and a readily derivatizable pyridyl-triazole ligand system. Experiments designed to probe the constitutional dynamics show that these architectures are in a non-equilibrium state. A preliminary investigation into the host-guest chemistry of a water-soluble derivative shows it can bind and differentiate a range of different neutral organic molecules. The stability of this ensemble also permits the study of guest-binding at high salt concentrations.
已使用一种先组装后氧化的方法，从钴（II）前体和易于衍生化的吡啶基三唑配体体系制备出了四面体钴（III）胶囊。旨在探究结构动力学的实验表明，这些结构处于非平衡状态。对一种水溶性衍生物的主客体化学进行的初步研究表明，它能够结合并区分一系列不同的中性有机分子。该体系的稳定性还使得在高盐浓度下研究客体结合成为可能。
