“…has resulted in the discharge of massive pollutants such as heavy metal ions into the natural environment, which brings a significant threat to human beings and living bodies. − For instance, the existence of Ag + in water may cause irreversible argyria and even lead to the liver injury, kidney damage, and epilepsy when an excessive silver ingestion occurs in humans. − Therefore, it is highly essential to design a facile and effective method for the fast recognition of targeted species. At present, though several detecting means, such as atomic absorption spectrometry, gas chromatography, and ion mobility spectrometry, have been developed, they suffer from inconvenience and a high-cost nature. , By contrast, luminescent chemosensors have been in high demand for contaminant monitoring recently, owing to their inexpensiveness, high accuracy, quick response, and excellent selectivity. − Consequently, pursuit of original and appropriate luminous materials for the specific metal sensing is of great importance and high urgency. On the other hand, developing nuclear industry brings about the emission of radioactive iodine, further causing a series of environment issues. − Apart from some strategies during iodine removal processes such as ion-exchange resin, extraction, and sodium filtration, the sorption method featuring ecofriendliness and high efficiency is regarded as a more competitive one.…”
