The macrocyclic nature of these molecules provides a well-defined internal cavity, into which smaller guest molecules can be included to form supramolecular host-guest inclusion complexes. The para-oriented attachment yields relatively rigid cylindrical or pillar-like molecular and cavity shapes, hence the name. In addition to the unique shape of these cavities (compared to the related meta-substituted calixarenes, for example), the aromatic nature of the cavity walls also contributes to distinctive host properties of pillar[n]arenes and guest affinities. Neutral pillar[n]arenes, such as those with alkyl substituents, are generally insoluble in water, and thus their host properties are studied in nonaqueous media. This review article will provide a comprehensive summary of the reported host binding studies of pillar[n]arenes in nonaqueous solution. A wide range of specific pillar[n]arenes have been studied in this way, as have a wide variety of sizes and types of guests. The emphasis will be on studies in which the value of the binding association constant K_a was measured and reported, to consider the effect of guest size, shape, and nature and the host size and substituents on the binding ability of pillar[n]arenes. The main objective of the paper is to provide a summary and overview of the host binding abilities of this fascinating family of molecular hosts in nonaqueous solution.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><img></picture></div></div></figure></div></div>","PeriodicalId":638,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"105 1-2","pages":"1 - 22"},"PeriodicalIF":2.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal–organic frameworks (MOFs), a vast category of high surface area microporous compounds, can be tailored to encapsulate specific active molecules, and control their release kinetics in the headspace of a product-package system for treatment and shelf-life extension of various agricultural produce. Hexanal has been widely reported to reduce post-harvest losses due to its antimicrobial, antifungal, ethylene-modulating, and phospholipase D (PLD) inhibiting characteristics. In this work, we synthesized Calcium-Squarate MOF by a quick simple mechanochemical process using bioderived linkers and non-toxic endogenous cations. We herein report the encapsulation of hexanal in Ca-Squarate MOF, and probe the strength of non-covalent host–guest interactions of hexanal encapsulated in the pores. The synthesized MOF crystals were characterized by thermal analysis, infrared spectroscopy, and diffraction studies. We observed approximately 20% encapsulation of hexanal by weight using thermo-gravimetric analysis. The infrared spectroscopy and simulation study supported the formation of hydrogen bonds between H atoms of hexanal and O atoms of the Ca-Squarate MOF with the strongest binding affinity of  −3.81 kcal mol⁻¹. Crystals maintained their porous structure and microscale morphologies post-encapsulation, as observed using X-ray diffraction and scanning electron microscopy.
