We report here the host-guest behaviour of two isoelectronic Fe4L4 tetrahedral cages that differ only in the nature of their face-capping ligand and possess either triazine (L1) or benzene (L2) cores. Crystallography reveals these hosts to be flexible and adaptable, while NMR spectroscopy shows them to be selective and discriminating in their host-guest behaviour.
我们在此报告两个等电子的Fe₄L₄四面体笼的主客体行为，这两个笼仅在其面封端配体的性质上有所不同，分别具有三嗪（L1）或苯（L2）核心。晶体学表明这些主体具有灵活性和适应性，而核磁共振光谱显示它们在主客体行为上具有选择性和区分性。
