摘要： AIE-active chemo sensors, according to the present teachings, exhibit UV-vis absorption change and become non-luminescent upon protonation. Upon deprotonation, the chemo sensors revert to their original absorption and emission. This deprotonation process can be triggered in the presence of amines, and specifically, biogenic amines. The chemo sensors can detect amine species, e.g., biogenic amines produced during food fermentation, quickly and with high sensitivity. Further, due to the AIE nature of the compounds, the chemosensors can be loaded onto a physical support and sealed inside a food package to monitor food spoilage.
