A cost-effective and innovative detector for iron ions†

Abstract

Severe environmental contamination can result from high concentrations of iron ions, which can have a detrimental impact on human health and well-being. Consequently, it is imperative to develop novel materials that can address environmental issues. Metal–organic frameworks (MOFs) possess unique properties that render them efficient fluorescent probes for the rapid and precise detection of these pollutants. A diverse array of MOF probes have been developed to detect iron ions. Nevertheless, their practical application is significantly impeded by the high production cost, which is a critical factor. This raises the question: why not implement a cost-effective, sensitive detector instead? Our research group has developed a novel MOF material, [Zn₂(bpy)(APA)₂(H₂O)]_n, that is specifically designed for MOF-based “off” sensors in aqueous media. This material not only demonstrates high sensitivity, and is manufactured from low-cost raw materials, but it also holds significant commercial potential, with production costs that are 98.4% lower than those of existing alternatives.
