“…Using the 3σ/B method, we calculated the lower limit of detection (LOD) of Zn 2+ as 66 nM (Figure 6b). In the existing literature reports, most LODs of fluorescence detection of Zn 2+ were between 9.85–2980 nm [ 33,48–56 ] ( Table 1 ; Figure S12, Supporting Information), and PAHZ‐OG prepared in our study have obvious advantages in the Zn 2+ detection limit.…”

The trace element Zn2+ plays an important role in the human body, but it is challenging to realize its qualitative and quantitative detection. Herein, inspired by the specific detection of the commercial dithizone to Zn2+, a series of polyacylhydrazones with polymerization‐induced emission (PIE) properties were successfully prepared and applied to the specific recognition and detection of Zn2+. It was found that all selected monomers did not emit fluorescence. In contrast, the as‐prepared polyacylhydrazone could emit strong fluorescence at 455 nm, due to the intramolecular aggregation of acylhydrazone groups along the macromolecular chains, indicating a significant PIE effect. As we expected, the polyacylhydrazone could specifically recognize and detect Zn2+ ions from 17 metal ions by the significantly enhanced fluorescence with a lower limit of detection (LOD) of 66 nM. Additionally, the complexation ratio of 2:1 between the repeating units in polyacylhydrazone and Zn2+, the coordination of Zn2+ with N and O atoms on acylhydrazone groups, and the fluorescence enhancement induced via intramolecular proton transfer were confirmed by 1H NMR and FT‐IR measurements. In conclusion, the successful preparation of PIE‐active polyacylhydrazones and the specific detection of Zn2+ ions provide a useful reference for the molecular design of new functional materials on the base of the traditional detection methods.This article is protected by copyright.

Three flexible coordination nanosheets, CoNinanosheet, Co-nanosheet, and Ni-nanosheet, were successfully synthesized using the liquid−liquid interfacial coordination method by the reaction of the ligand, 1,1,2,2-tetrakis(4-(2,2′:6′,2″-terpyridyl)phenyl)ethylene with nickel(II) and cobalt-(II) nitrates. The effective coordination between the ligand and metal ions is confirmed using characterization techniques including Fourier transform infrared spectra, X-ray photoelectron spectroscopy, scanning electron microscopy, and atomic force microscopy. The bimetallic nanosheet, CoNi-nanosheet, demonstrates an exceptional specific capacity of 112.0 mA h g −1 at 1 A g −1 . Furthermore, the CoNi-nanosheet maintains a capacity retention of 70.07% at 5 A g −1 after 1000 cycles. Upon integration into an asymmetric supercapacitor configuration, the CoNi-nanosheet assembly attains a heightened energy density of 89.0 W h kg −1 at a power density of 800 W kg −1 . Impressively, the asymmetric supercapacitor has great stability. The excellent electrochemical performance of the bimetallic CoNi-nanosheet is likely attributed to alterations of electron densities around Co 2+ and Ni 2+ ions.
