“…Dithieylethene-based photoswitches responding to a single ion are more desirable for the specific detection of target ions of interest. For instance, calcium as one key element in many environmental and biological processes [110][111][112][113][114][115] is also of great significance for its highly specific monitoring. It was shown that diarylethene-based sensors are capable of detecting Ca 2+ with absorbance change as the output signal.…”

“…[48,49] Although, to date, a number of studies have fruitfully been presented related to the cation recognition by utilizing the photoswitchable receptors, but only limited reports are available for anion as well as ion-pair receptors using such photoresponsive systems (Figure 8). [50][51][52][53][54][55][56][57] Kokan's research group has reported the synthesis of a novel 2,6-pyridine bisamide supported 2-pyridyl acylhydrazone based photoswitchable heteroditopic ion-pair receptor 58, having a low molecular weight, and was easily achieved from the commercially available precursors (Figure 9). [58] This versatile receptor exhibited two stable configurational E-isomer (binding) and Z-isomer (non-binding form), and displayed strong binding towards metal salts with high cooperativity in acetonitrile solution.…”

Over the past two decades, non‐covalent chemistry has introduced various promising artificial receptors and revolutionized the host‐guest chemistry. These versatile receptors have particularly been entertained in sensing and recognizing of diverse neutral molecules and/or ionic entities (e. g. anions, cations and ion‐pair) of particular interest. Notably, supramolecular chemistry had given birth to a plethora of important molecules, explored in the chemical, biological, environmental, and pharmacological world to resolve the critical issues related to the human health while keeping environmental concerns in mind. Amongst the various types of supramolecular monotopic receptors (anions, cations, and neutral molecules), heteroditopic receptors (ion‐pair receptors) consisting of distinct binding sites in one system for both cation and anion, have gained much interest from the scientific community in recent past because of their unique binding abilities. Interestingly, these promising artificial receptors have shown potential applications in sensing, recognition, transport and extraction processes besides their uses in salt/waste purification. Bearing the importance of these systems in mind, we intended to report the recent developments in ion‐pair chemistry. Herein, we divided the whole document into three main sections; first one describes the introduction and history of the ion‐pairs receptors. The second portion highlights the synthesis and applications of ion‐pair receptors in sensing, recognition, molecular machines, photoswitching behaviour, extraction and transport properties, whereas the last part of this manuscript provides concluding remarks as well as future prospects of ion‐pair receptors. We hope that this manuscript will be helpful to stimulating researchers around the globe to find out the hidden opportunities in this and related areas.

“…[23][24] Through monitoring the signal changes in colorimetric and fluorometric wavelength or intensity, the presence of nerve agents can be clearly detected by chemosensors with low limit of detection (3σ/k), therefore, these methods had been widely explored in the past decades. [25][26][27][28][29][30][31][32][33][34][35] Due to the fatality of the real nerve agents, it is prohibited to investigate such reagent directly without professional training and biological safety protection third-level laboratory. Thus, common laboratories typically employed the nerve agent simulants with less toxicity, such as diethyl chlorophosphate (DCP), diethyl cyanophosphate (DCNP) to mimic G nerve agents, demeton-S-methyl (DSM) to mimic VX nerve agents as representatives for study.…”

Nerve agents are a branch of organophosphorus (OP) compounds that chemically cause irreversible inhibition of acetylcholinesterase, thereby failing the hydrolysis of acetylcholine, resulting in severe neurological disease and death in organisms. Thus, the unreasonable use of such compounds threatens public and national security, so it is a high demand to establish portable, low‐cost, sensitive, and highly selective methods for their precise detection. In this review, we introduced the recent development of spectroscopy‐based optical chemosensors that aimed for the detection of nerve agents, focusing on the progress made in the molecular design, sensing principle and applications. We conclude this Review by highlighting the current challenges associated with the future development and outlook.
