The present invention provides calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles, having 4, 5, 6, 7, or 8 heterocyclic rings, as well as syntheses, derivatives. conjugates, multimers, and solid supports thereof. Such macrocycles have proved to be effective and selective ion- and neutral molecule-binding agents forming supramolecular ensembles, and ion- and neutral molecule-separation agents. The macrocycles are fully meso-non-hydrogen-substituted porphyrinogens, a few molecules of which were previously known but not recognized as possessing anion- or molecule-binding properties. The binding mode is noncovalent, primarily that of hydrogen-bonding, thereby providing a new mode for liquid chromatography, that of Hydrogen Bonding Liquid Chromatography. Further useful applications of the macrocycles provided herein include environmental remediation by removal of undesired ions or neutral molecules, and removal of phosphate for kidney dialysis.
本发明提供了具有4、5、6、7或8个杂环环的卡利克斯吡咯、卡利克斯吡啶吡咯和卡利克斯吡啶大环,以及它们的合成、衍生物、共轭物、多聚体和固体支持物。这些大环已被证明是有效的和选择性的离子和中性分子结合剂,形成超分子集合体和离子和中性分子分离剂。这些大环是完全的介质-非氢取代的卟啉原,之前已知其中的一些分子,但未被认为具有阳离子或分子结合性质。结合模式是非共价的,主要是氢键结合,从而提供了液相色谱的新模式,即氢键液相色谱。本文提供的大环的进一步有用应用包括通过去除不需要的离子或中性分子来进行环境修复,以及通过去除磷酸盐来进行肾透析。
