A Review on MOFs as Efficient Fluorometric Chemosensors for Metal Ions

Abstract MOFs are extensively utilized for recognizing metal ions. With their tunable structures, opportunities for postsynthetic modification, and chemical stability, MOFs outperform current alternatives by providing unique spectroscopic readings for metal ion detection. We find their recyclability particularly appealing, as it allows repeated use of the same host probe—this aspect is crucial for point‐of‐care technologies. This review offers an in‐depth exploration of metal ion recognition through MOFs, including insights into sensing mechanisms and photophysical properties sourced from more than 130 articles. It serves as a valuable reference for those interested in a comprehensive understanding of knowledge.
