The construction of chemical sensors that can distinguish molecular chirality has attracted increasing attention in recent years due to the significance of chiral organic molecules and the importance of detecting their absolute configuration and chiroptical purity. The supramolecular chirality sensing strategy has shown promising potential due to its advantages of high throughput, sensitivity, and fast chirality detection. This review focuses on chirality sensors based on macrocyclic compounds. Macrocyclic chirality sensors usually have inherent complexing ability towards certain chiral guests, which combined with the signal output components, could offer many unique advantages/properties compared to traditional chiral sensors. Chirality sensing based on macrocyclic sensors has shown rapid progress in recent years. This review summarizes recent advances in chirality sensing based on both achiral and chiral macrocyclic compounds, especially newly emerged macrocyclic molecules.

Palladium@Gold nanoparticles modified three-dimensional-reduced graphene oxide (3D-rGO/Pd@Au) was coupled with carboxymethyl-β-cyclodextrin to form a novel nanocomposite (3D-rGO/Pd@Au/CM-β-CD). The 3D-rGO/Pd@Au/CM-β-CD has been served as a chiral sensing interface for electrochemical enantiorecognition...

A series of aniline-based macrocycles (An[2]s) were synthesized and applied to iodine capture. An[2]s showed remarkable iodine uptake capacities of up to 7.35 g·g−1 in the vapor phase and significantly...

A series of cyclodextrin dimers (6-NDI-CDs) that were bridged by 1,4,5,8-naphthalenediimide (NDI) were synthesized. Photoirradiation of 6-NDI-CDs in an aqueous solution led to a color change from almost colorless to...
