The use of supramolecular macrocycles to construct multifunctional nanomaterials has attracted extensive attentions.As a new developing family of macrocyclic hosts,the synthesis and application of pillar[n]arenes are particularly important.The electronic characteristics of easy functionalization and adjustable internal cavities enable them to bind with a variety of guest molecules and to selectively complex with metal ions through non-covalent interactions,thereby endow them with excellent properties and functions.This review summarizes the research progress in the preparation of pillar[n]arene-based nanomaterials and their applications in sensing.The problems existing in the synthesis of pillar[n]arene are discussed,and the direction of research and development is prospected.
