ABSTRACTIn this study, two structurally similar ‘turn on’ fluorescent probes B1 and B2 with high binding energy with Al3+ were synthesised. With new thiazole substituted salicylaldehyde fluorophore, these two hosts also have good selectivity and sensitivity in the detection of Al3+ based on the chelating fluorescence-enhancing effect under test conditions. They show an extremely low detection limit, 0.478 nM and 4.04 nM, respectively, with binding constants of 2.34 × 106 M−1 and 1.36 × 106 M−1. A 1:1 binding ratio of dual probes to Al3+ was demonstrated by working curves and mass spectrometry. The mechanisms were confirmed by 1H NMR and DFT calculations, defined that both two compounds combined with Al3+ by two oxygen atoms (one in C=O and another in -OH) and one nitrogen atom in -NH group to form triple coordination structure. Further application in test strips, actual soil and traditional Chinese medicine (TCM) suggest probes B1 and B2 have well application prospects in detecting Al3+.KEYWORDS: Al3+ detectionfluorescent probeSchiff baseCHEF mechanism AcknowledgmentsThis work is supported by the National Natural Science Foundation of China (51863004) and the Natural Science Foundation of the Guizhou Science and Technology Department (JZ [2018]1077).Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/10610278.2023.2270600.

ABSTRACTDyes are a class of hazardous chemicals that can cause harm to the environment and life on earth. However, it remains a huge challenge for the effective removal of the dyes. Herein, a new metal-organic capsule {[Cu(L)(bpy)(H2O)]·H2O}n (1) was synthesised by (4,4’-(((1,3,4-thiadiazole-2,5-diyl)bis(sulfanediyl))bis (methylene)) dibenzoic acid, 2,2’-bipyridine and CuCl2∙2 H2O under solvothermal condition. Interestingly, two inversion asymmetric units are connected by O-H···O and O-H···N to form a centrosymmetric capsule with cavity. The intermolecular interactions were further quantitatively analysed and visualised by the CrystalExplorer 17.5. Notably, complex 1 can effectively adsorb methylene blue (MB), and the adsorption performance is linearly correlated with MB concentration. When the concentration of MB was increased from 10 to 50 mg∙L−1, the adsorption performance of 1 was increased from 17.68 to 66.79 mg∙g−1, while reduced the MB removal efficiency from 88.4% to 66.4%. The adsorption process is suitable for the pseudo-second-order and the Langmuir model. Furthermore, complex 1 showed the good recyclability and stability for at least five runs.KEYWORDS: Metal-organic capsulehydrogen bondingπ-π stackingHirshfeld surface analysisdyes adsorptionmethylene blue Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/10610278.2023.2260042.Additional informationFundingThis work was supported by the [National Natural Science Foundation of China] under Grant [number 21771096].

Allostery – the control of macromolecule conformation and function by the remote binding to an effector molecule – allows numerous biological machines to carry out their roles in the body. Writing in Chem, Cheng-Yong Su and colleagues have described a metallo-amine cage (MOC-68, Figure 1) that exhibits intricate, proton-driven allostery underpinned by water binding and release [1], with implications in controlled guest binding, transport and release. MOC-68 (Figure 1) comprises flexible, amine corners and face-capping metalloligands containing imidazole linkers; thus, numerous acid/base sites are accessible. When protonated, these sites bind water molecules which rigidify the cage; when deprotonated, water is released and the conformational flexibility of the cage increases. The initial state can only bind guests on the exterior of the cage (exo-binding); however, pH-driven allosteric switching provides a larger cavity, allowing endobinding. Interestingly, the corners of the cage can be capped with CB[10], yielding a rare ‘ring-on-cage’ system. This locks the conformation of the cage, can trigger the release of endo-bound guests, and prevents allosteric switching and endo-guest binding. Another consequence of the changes in protonation state is that the charge of the cage can be drastically altered by changing the pH. This affects the polarity of the system and means that the cage can reversibly phase transfer from polar to non-polar solvent mixtures.

ABSTRACT The appreciation of the central role of Coulombic interactions in enzyme catalysis has led to the development of many ‘spin-off’ strategies for controlling chemical reactions. In particular, supramolecular chemistry has become increasingly proficient in using encapsulation/compartmentalisation to control both stoichiometric and catalytic reactions within the inner-spaces of hosts. This noted, there are still many open questions around the design of electrostatic potential fields within such hosts, and how exogenous factors can be used to fine-tune these properties. Here, we report on the cyclisation of 12-bromododecane-1-thiol 2 inside supramolecular capsule 1 2 to give thiacyclotridecane 3, and how the rate of this reaction changes as a function of exogenous salts. We find that this cyclisation is slowed in the presence of exogenous anions, with attenuation being highly dependent on both their nature and concentration. Thus, this work demonstrates how anions at the more-weakly solvated end of the Hofmeister series can associate with the outer walls of the capsule and so attenuate cyclisation. This suggests new ways in which reactions in inner-spaces can be indirectly modulated by exogeneous chemical entities. GRAPHICAL ABSTRACT
