“…Density functional theory calculations were performed to further understand the bonding nature of the sensor R -β-D- 1 with Bi 3+ . The density functional of B3LYP/6-31G was carried out using the program Gaussian 09W, and the dispersion correction of GD3BJ was taken into account to calculate the structure and energy levels of the sensor R -β-D- 1 before and after coordination with Bi 3+ [ 39 ]. The structure of the sensor R -β-D- 1 after optimization is shown in Figure 7 a.…”

A novel fluorescent “off” probe R-β-D-1 containing a 1,2,3-triazole moiety was obtained by the Click reaction with azidoglucose using H8-BINOL as a substrate, and the structure was characterized by 1H NMR and 13C NMR and ESI-MS analysis. The fluorescence properties of R-β-D-1 in methanol were investigated, and it was found that R-β-D-1 could be selectively fluorescently quenched by Bi3+ in the recognition of 19 metal ions and basic cations. The recognition process of Bi3+ by R-β-D-1 was also investigated by fluorescence spectroscopy, SEM, AFM, etc. The complex pattern of R-β-D-1 with Bi3+ was determined by Job’s curve as 1 + 1, and the binding constant Ka of R-β-D-1 and Bi3+ was valued by the Benesi–Hildebrand equation as 1.01 × 104 M−1, indicating that the binding force of R-β-D-1 and Bi3+ was medium. The lowest detection limit (LOD) of the self-assembled H8-BINOL derivative for Bi3+ was up to 0.065 µM. The mechanism for the recognition of Bi3+ by the sensor R-β-D-1 may be the intramolecular charge transfer effect (ICT), which was attributed to the fact that the N-3 of the triazole readily serves as an electron acceptor while the incorporation of Bi3+ serves as an electron donor, and the two readily undergo coordination leading to the quenching of fluorescence. The recognition mechanism and recognition site could be verified by DFT calculation and CDD (Charge Density Difference).

“…Due to the restrain of the intramolecular vibration and rotation of ligands by the aggregation, the emission of Au/Ag NCs could be enhanced. PPi, containing two phosphate groups, could coordinate well with Zn 2+ (Xu et al, 2020 ). Therefore, when PPi were present, they could competitively bind with Zn 2+ and remove Zn 2+ from aggregates.…”

“…In our study, Zn 2+ could effectively cause the aggregation of Au/Ag NCs via the electrostatic interaction between Zn 2+ and ligands on the surface of Au/Ag NCs, thereby enhancing the luminescence of Au/Ag NCs. When PPi was added to the Zn 2+ -Au/Ag NCs aggregates, the coordination of Zn 2+ and PPi would remove Zn 2+ from aggregates (Dong et al, 2017 ; Xu et al, 2020 ), resulting in the destruction of aggregates and the decrease of luminescence intensity of Au/Ag NCs. According to the relationship between the fluorescence intensity and the concentration of PPi, the detection of PPi was achieved.…”

The development of sensitive and accurate detection of inorganic pyrophosphate (PPi) and pyrophosphatase activity (PPase) is important as they play vital roles in biological systems. However, it is still not satisfactory for most of the analytical methods for PPi and PPase because of their Cu2+-dependence and poor accuracy. Although the metal ion triggered aggregation-induced emission (AIE) of metal nanoclusters (NCs) offers a new approach to design a Cu2+-free strategy for the accurate determination of PPi and PPase recently, current methods are all focused on utilizing pure metal NCs. Alloy NCs incorporating the advantages of diverse metal usually can achieve improved behaviors in the application, such as enhanced sensitivity and stability. In this work, glutathione stabilized alloy Au/Ag NCs were synthesized via a simple method and used for the fluorescence detection of PPi and PPase based on a Zn2+-regulated AIE strategy. The controlled release of Zn2+ by PPi and PPase could regulate the AIE of Au/Ag NCs and be employed to response PPi concentration and PPase activity. This method processes simple procedure, high sensitivity and stability, and low toxicity. In addition, we also studied the AIE behaviors of this Au/Ag NCs and offer some fundamental understanding of the AIE properties of water-soluble alloy NCs. This study not only provides a straightforward and new approach for PPi and PPase determination but a basis for further study on the AIE properties of alloy NCs and their application.

The advancement of optical chemosensors has achieved success with the advent of Supramolecular Chemistry. Unlike other scaffolds, the 1,8‐naphthalimide motif has emerged as an excellent fluorescent chemosensor due to its photophysical properties like thermostability, cytotoxicity, membrane permeability, selectivity, and sensitivity. The naphthalimide scaffold is distinctive in its ways of tracking biological analytes and diagnosing its role in various diseases. This review provides insight into current developments in the synthesis and designing of 1,8‐naphthalimide‐based chemosensors for the recognition of metal ions, its mechanistic approach for its sensitivity, selectivity, and practical applications in a real environment. We hope that this review will aid to develop a novel approach to sense toxic analytes in real water samples and improve real‐time applications.
