octamethylferrocenium cation or decamethylcobaltocenium cation exhibited different phase sequences from those of the corresponding decamethylferrocenium salts. Structural changes associated with the phase transitions were investigated crystallographically for twosalts. The phase transition in [Fe(C5Me5)2](CF3SO3) at −121.6 °C was accompanied by ordering of the cation conformations into eclipsed and staggered

report a series of hosts equipped with dual guest selection mechanisms. These hosts simultaneously possess a preorganized binding cavity and a confined ion translocation tunnel, which are crucial to the record-setting K+/Na+ selectivity and versatile capabilities to discriminate against a wide range of ion pairs, such as K+/Rb+, K+/Ba2+, and Rb+/Cs+. Mechanistic studies verify that the host’s portal is capable
对识别事件在时间和空间上发展的规则对于活生物体至关重要。在进化过程中,生物体发展出独特的正交机制来实现选择性识别,从而避免了相互干扰。尽管将多种选择机制合并到单个人工宿主中可能会导致具有无与伦比的选择性的适应性更强的识别系统,但是这种策略的成功实施很少见。受两种著名的生物离子结合剂(缬霉素和K +通道)的有趣结构和识别特性的启发,我们在此报告了一系列配备双重客体选择机制的宿主。这些宿主同时具有预组织的结合腔和受限的离子易位通道,这对于创纪录的K至关重要+ / Na +的选择性和通用功能,可区分各种离子对,例如K + / Rb +,K + / Ba 2+和Rb + / Cs +。机理研究证实,宿主的门户能够根据阳离子的大小区分阳离子,从而实现不同的离子吸收速率。带有连续结合位点的密闭隧道在将离子包入掩埋腔的过程中促进了离子的完全去溶剂化,从而模拟了离子通道内的离子易位。我们的结果表明,在平衡
