Recently, more and more rhodamine derivatives have been used as fluorophores to construct sensors due to their excellent spectroscopic properties. A rhodamine‐basedfluorescent and colorimetric Fe3+ chemosensor 3’,6’‐bis(ethylamino)‐2‐acetoxyl‐2’,7’‐dimethyl‐spiro[1H‐isoindole‐1,9’‐[9H]xanthen]‐3(2H)‐one (RAE) was designed and synthesized. Upon the addition of Fe3+, the dramatic enhancement of both

A rhodamine triazole-based fluorescentchemosensor has been developed for the selective detection of platinum ions in aqueous solutions. The rhodamine 6G hydroxamate linked with a propargyl group is converted to the corresponding triazole by a “click” reaction. The dual binding unit composed of a hydroxamate and a triazole shows high selectivity and sensitivity toward Pt2+ over a range of other metal

A new rhodamine-hydroxamic acid-based fluorescent chemosensor for the rapid detection of HOCl in aqueous media was developed. The system, which utilizes an irreversible HOCl-promoted oxidation reaction, responds instantaneously at room temperature with linear proportionality to the amount of HOCl. This system is highly selective for HOCl over other reactive oxygen species (ROS) and highly sensitive in aqueous solutions. Biological imaging studies using living cells and organisms (A549 cells and zebrafish) to detect HOCl are successfully demonstrated.
