Abstract

1,2,3‐Triazole‐based ligands obtained through copper(I)‐catalyzed azide‐alkyne cycloaddition (CuAAC) have been exploited in vast array of research domains owing to the stitching of simpler molecules through a needle of Cu(I) catalyst. The numerous reports on ion(s) detection capabilities of synthesized 1,4‐disubstituted 1,2,3‐triazole ligands using absorption and fluorescence spectroscopy are accessible. This review enlists substituted 1,2,3‐triazole‐based sensor probes, since 2010, synthesized selectively by CuAAC, having the ability to sense either a single ion or multiple ions under specific set of conditions along with their detection limits. The review also apprehends the different techniques and sensing mechanisms involved in the detection of ions by chemosensor probes.
