Abstract

Calix[4]arenes and calix[4]resorcinarenes are well-known macrocyclic hosts that can be tailored to bind guests of very different natures, including anions, cations, and various neutral molecules. The molecular architectures of the hosts can be altered in many ways: by attaching polar or hydrophilic groups, extending inner cavities with enlarged aromatic side walls, and adding H-bonding sites to promote the formation of molecular capsules. The attachment of different types of redox-active moieties renders calix[4]arene and calix[4]resorcinarene derivatives electrochemically active, enabling them to either control the guest-binding properties of the receptors or be used as electrochemical sensors. This review will focus on calix[4]arene and calix[4]resorcinarene macrocyclic hosts with appended redox-active groups, such as ferrocene, tetrathiafulvalene, and quinone. We will discuss molecular receptors that can serve as redox sensors for cations or electron-deficient molecules or can bind and release their guests controlled by redox or electrochemical stimuli.

基于杯[4]芳烃和杯[4]间苯二酚芳烃支架的氧化还原响应性大环主体
钙并[4]烯和钙并[4]间苯二酚是众所周知的大环宿主,它们可以进行定制,以结合不同性质的客体,包括阴离子、阳离子和各种中性分子。可以通过多种方式改变宿主的分子结构:附加极性或亲水基团、扩大芳香族侧壁以扩展内腔,以及添加 H 键位点以促进分子胶囊的形成。附着不同类型的氧化还原活性分子可使钙并[4]炔和钙并[4]间苯二酚衍生物具有电化学活性,使它们能够控制受体的客体结合特性或用作电化学传感器。本综述将重点讨论带有氧化还原活性基团(如二茂铁、四硫富缬烯和醌)的钙[4]炔和钙[4]间苯二酚大环宿主。我们将讨论可作为阳离子或缺电子分子氧化还原传感器的分子受体,或可在氧化还原或电化学刺激的控制下结合和释放客体的分子受体。

期刊介绍: The fledgling State of Israel began to publish its scientific activity in 1951 under the general heading of Bulletin of the Research Council of Israel, which quickly split into sections to accommodate various fields in the growing academic community. In 1963, the Bulletin ceased publication and independent journals were born, with Section A becoming the new Israel Journal of Chemistry. The Israel Journal of Chemistry is the official journal of the Israel Chemical Society. Effective from Volume 50 (2010) it is published by Wiley-VCH. The Israel Journal of Chemistry is an international and peer-reviewed publication forum for Special Issues on timely research topics in all fields of chemistry: from biochemistry through organic and inorganic chemistry to polymer, physical and theoretical chemistry, including all interdisciplinary topics. Each topical issue is edited by one or several Guest Editors and primarily contains invited Review articles. Communications and Full Papers may be published occasionally, if they fit with the quality standards of the journal. The publication language is English and the journal is published twelve times a year.
