“…The peaks at 873 cm À1 and 752 cm À1 were assigned to symmetrical and asymmetrical stretching vibrations of the naphthalene ring. 29,30 By blending SPO with PMMA, the relevant characteristic peaks confirmed that PMMA-SPO fibers had been successfully fabricated. After the PMMA-SPO fiber was irradiated by UV, the peaks representing CQN at 3450 cm À1 and 1632 cm À1 almost disappeared, indicating that PMMA-SPO involved a ringopening reaction.…”

“…Among them azobenzenes, spiropyrans, furylfulgides, and diarylethenes are being considered as the most potential photoresponsive materials due to their excellent thermal stability, photoreactivity, fatigue resistance, and rapid responses. [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).…”

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.

“…[4] In addition, many synthetic compounds have 3-amino-1,2-diol moieties in their backbones, including the antitumor agent aminocyclopentitol pactamycin, the proteasome inhibitor TMC-95 A, the immunosuppressant antibiotic myriocin, riboflavin (vitamin B2) and the hydrogenase coenzyme F420. [5] Besides being of pharmacological interest, 3amino-1,2-diols have proven to be excellent building blocks for the synthesis of various heterocyclic compounds such as 1,3oxazine, [6,7] 1,3-thiazine [8] and pyrimidines. [9] Pyrimidines belong to an important class of heterocyclic structures found in many synthetic and naturally occurring products with a remarkable spectrum of biological activities.…”

A series of novel heterocyclic structures, namely 1,3‐oxazines, 1,3‐thiazines and 2,4‐diaminopyrimidines, were designed and synthesised. The bioassay tests demonstrated that, among these analogues, 2,4‐diaminopyridine derivatives showed significant antiproliferative activity against different human cancer cell lines (A2780, SiHa, HeLa, MCF‐7 and MDA‐MB‐231). Pyrimidines substituted with N 2 ‐( p ‐trifluoromethyl)aniline, in particular, displayed a potent inhibitory effect on the growth of cancer cells. Structure–activity relationships were also studied from the aspects of stereochemistry on the aminodiol moiety as well as exploring the effects of substituents on the pyrimidine scaffold.
