“…13c) in a unique fashion. Various groups have been engaged in the development of chemosensors based around macrocyclic receptor scaffolds which include polyamines, calixarenes, calixpyrroles and porphyrins [48][49][50][51][52][53][54][55][56]. Kataev and co-workers proposed the bicyclic, anthracene-containing receptor 21 as an OFF-ON chemosensor for nitrate in buffered aqueous solution [57].…”

In this review we cover recent developments in fluorescent and colorimetric anion sensors. These systems employ a range of different non-covalent interactions including hydrogen-and halogen-bonding, Lewis acidic boron-based sensors, metal-based sensors, charged systems, compounds that use anion-pi interactions to stabilise complexes, photoswitchable systems, the use of excimers and molecular logic gates in sensing. Recent developments in anion-selective chemodosimeters are also surveyed.

Constructing novel antibiotic switches is of great importance to fighting bacterial infections and reducing the public health threat caused by antibiotic abuse. In this work, a plug‐and‐play antibiotic switch based on the host‐guest interaction between berberine hydrochloride (BBR) and cucurbit[7]uril (CB[7]) is reported. BBR can be encapsulated in the cavity of CB[7] to form BBR@CB[7] with enhanced fluorescent emission and reduced antibacterial activity. And BBR can be released from BBR@CB[7] in the presence of other competitors, such as amantadine hydrochloride (ADA). The self‐assemble and disassemble ability of the supramolecular complex can be applied as facile plug‐and‐play antibiotic switch to “turn‐on” and “turn‐off” its antibacterial activity on demand. This work provides a simple, rapid, and efficient strategy for antibacterial regulation through supramolecular chemistry.
