Recognition of trivalent analytes using simple organic chromogenic and fluorogenic probes: A review

Abstract

Trivalent analytes such as Fe3+, Cr3+ and Al3+ play pivotal roles in various fields including environmental monitoring, biological sensing, and industrial processes. The development of efficient and selective detection methods for trivalent species is therefore of paramount importance. In this review, we present an overview of recent advances in the recognition of trivalent analytes using simple organic chromogenic and fluorogenic probes. In this review we discuss the strategies employed for the design and synthesis of chromogenic and fluorogenic probes tailored for trivalent analytes, highlighting key structural motifs and functional groups that contribute to their recognition capabilities.
