以阴离子为模板的水性自组装导致了由氮杂磷杂环戊二烯基亚组分形成内外官能化的Fe II 4 L 4四面体。这种新的水溶性笼是柔性的并且能够与体积从35到219埃包封阴离子3通过氢键和静电相互作用。它可根据模板阴离子的大小和形状在结构上进行调整,并动态采用构象,其中所有四个氮杂磷杂环丁烷+P–H向量指向内部,否则一个指向外部,其他三个指向内部。两种笼型异构体可以共存于溶液中并相互转化。在来宾移位期间观察到形状记忆现象,因为来宾交换比结构重新配置发生得更快。

protonated tripodal scaffold encapsulates small solvent molecules and helps in side-cleft binding of the larger sulfate anion. Herein, we report the design, synthesis and characterization of tren-based polyammonium receptors L1, L2 and L3 and their complexation as well as binding discrepancy with several anions in the presence of acid. The solid state crystal structure of the anion complexes with L1, L2 and

the formation of an endohedrally functionalized FeII4L4tetrahedron from azaphosphatrane-based subcomponents. This new water-soluble cage is flexible and able to encapsulate anions with volumes ranging from 35 to 219 Å3 via hydrogen bonding and electrostatic interactions. It structurally adapts in response to the size and shape of the template anions, dynamically adopting a conformation either where
