Recent Advancements in Schiff Bases as Chemosensors

Chemosensor is a molecule or device that detects or responds to chemical species known as analytes. Chemosensors bind to specific analytes, triggering a measurable response. Schiff bases are widely explored as chemosensors due to unique properties such as chelating ability and binding to analytes including metal ions. The Schiff base can form a conjugated system, leading to a change in optical properties upon binding with analytes. Schiff bases exhibit fluorescence properties, making them suitable for optical sensing applications. Beside medicinal and biological applications, several Schiff bases are reported for the detection of analytes such as metal ions, anions, and nitroaromatic compounds. Schiff bases are inexpensive, easy to synthesize, and readily available laboratories.
