“…SWJT-31 was soluble in DMSO, but almost insoluble in water, so the AIE performance of SWJT-31 was determined by increasing the water fraction. 46 In order to determine the excitation wavelength of the AIE channel, the absorption spectra of SWJT-31 in 99% HEPES solution were studied (Fig. S5, ESI†).…”

“…Luminescent sensors of metal ions offer high sensitivity, relatively low cost, simple operation, and rapid response times. − Most classic organic dyes used for sensing applications undergo strong π–π stacking interactions and are quenched at higher concentrations or in the aggregated state, which is referred to as aggregation-caused quenching (ACQ) . Luminescent materials with aggregation-induced emission characteristics (AIEgens) generally display weak or no emission in solution but strongly emit in an aggregated state, providing an alternative sensing mechanism. − In recent years, various AIEgens have been developed and served as advanced functional materials for bioimaging, disease theranostics, as well as for metal ion sensing and environmental monitoring. − …”

Luminescent materials with aggregation-induced emission (AIE) characteristics have been recognized as highly selective and sensitive probes for the detection of toxic metal ions in recent years. In this paper, a Au−Ag cluster-based coordination polymerwas prepared by in situ generation of the diphosphine N-heterocyclic carbene (PC NHC P)-type ligand L in the presence of the corresponding metal salts. Compound 1 exhibited 530 nm phosphorescence under 380 nm excitation with a QY of 6.30% and a lifetime (τ) of 7.14 μs in the solid state. 1 showed good AIE behavior in the mixture of MeOH/H 2 O while the best aggregation state (f water = 90%, QY = 6.79%, τ = 6.70 μs) exhibited selective and sensitive emission quenching toward Cr(VI) ions. Ultralow detection limits of 9.7 ppb (w/ w) for Cr 2 O 7 2− and 17.9 ppb (w/w) for CrO 4 2− were achieved.

Abstract5‐N,N‐diarylaminothiazoles containing cyano and nitro groups were synthesized using the Pd‐catalyzed Buchwald‐Hartwig amination reaction with good yields. The cyano group in the resultant thiazole was reduced to a formyl group. This was then subjected to the Knoevenagel condensation reaction, leading to the formation of thiazoles with a dicyanovinyl group. The nitro group in the thiazole was reduced to an amino group, which was subsequently reacted with triphosgene, yielding a thiazole with an isocyanate group. These thiazoles, with their electron‐accepting properties, demonstrated absorption and emission spectra at longer wavelengths. Notably, the thiazole containing the dicyanovinyl group displayed a red emission. Tests for the detection of hydrazine, a hazardous volatile organic compound, were conducted using the synthesized thiazoles. The results showed that the dicyanovinyl group effectively responded to hydrazine hydrate, evidenced by changes in the absorption and emission spectra. This change in color was also visibly detectable to the naked eye.
