ABSTRACT Macrocyclic molecules possess preorganised cavities that inherently enable them to bind volatile small molecules that are complementary in size and shape. Integrating such macrocyclic receptors with an electrical signal transductor represents a promising strategy to fabricate electrical vapour sensors with high selectivity and sensitivity. The application of calixarenes, cyclodextrins, porphyrins, and deep cavitands for this application have been investigated. The electrical vapour sensor devices based on these macrocycles demonstrated promising performance towards specific analytes. Some highly selective examples can distinguish isomeric analyte molecules with only minute structural differences. Besides selectivity, certain sensors also demonstrated ppb level sensitivity. This review highlights the progress in electrical vapour sensing using macrocyclic molecular receptors, along with outlook to the future directions for the field. Graphical Abstract

大环分子受体的电蒸汽传感

摘要 大环分子具有预先组织的空腔，固有地使它们能够结合大小和形状互补的挥发性小分子。将这种大环受体与电信号转导器相结合代表了制造具有高选择性和灵敏度的电蒸汽传感器的有前途的策略。已经研究了杯芳烃、环糊精、卟啉和深空腔在该应用中的应用。基于这些大环的电蒸汽传感器装置对特定分析物表现出有希望的性能。一些高度选择性的例子可以区分同分异构分析物分子，只有微小的结构差异。除了选择性之外，某些传感器还表现出 ppb 级的灵敏度。本综述重点介绍了使用大环分子受体进行电蒸汽传感的进展，以及对该领域未来方向的展望。图形概要
