“…High intake could also cause anemia and gastrointestinal distress and elevates the risk of lung cancer [17]. Many chemosensors have been reported for sensing Cu 2+ [7,[18][19][20][21][22][23] but a convenient, fast, and accurate method is yet to be developed for its detection as this matter is of considerable importance. Sahoo's group reported chemosensor 1 for selective detection of Cu 2+ in an aqueous medium [24].…”

Metal ions are widely distributed in living organisms and environmental systems, therefore, their monitoring is of great importance. These days, several sophisticated instrumental methods are being used for the detection of metal ions; however, rapid recognition of metal ions requires powerful tools namely, colorimetric and fluorescent chemosensors. In this review, Rhodamine B and Rhodamine 6G based colorimetric and fluorescent chemosensors have been discussed. These methods are simple, involve low cost, lower detection limit, high selectivity, and sensitivity, thereby used to monitor real-time metal ions. Several metal ions were detected with high selectivity and sensitivity with the aid of various derivatives of Rhodamine B and Rhodamine 6G fluorophores conjugated to different ligands. Besides that, this review is focused on the detection of Cu 2+ metal ions in recent years.

“…[10,11] Hence, it is not surprising to witness an array of rhodamine-based copper sensors in the literature. [12][13][14][15][16] Due to the obvious photo-response upon metal coordination, fluorescent and colorimetric sensors based on rhodamine derivatives have been approved for the detection of Cu 2 + . [17][18][19][20][21][22][23] Despite the development of various Cu 2 + sensors, majority of them exhibit a "turn-off" response as Cu 2 + often functions as a quencher through an energy or electron transfer mechanism.…”

Rhodamine-based chromic materials have attracted significant interest owing to their cation recognition ability with high sensitivity. However, rhodamine chromophores with controllable sensing selectivity towards transition metal species are only at the advent. Herein, three triazoleconjugated rhodamine dyads with different peripheral substituents were synthesized. The key triazole precursors required for the desired chemistry were prepared by adopting our recently developed CTAB catalyzed mechanoclick chemistry. Molecular properties derived from photo-physics, electrochemistry and surface morphology of the synthesized dyads were analyzed. Furthermore, frontier molecular orbitals, electronic structure and secondary quantum chemical parameters of dyads were also compared. Screening of dyads for their sensing ability towards an array of alkali, alkaline and transition metal ions exhibited a noticeable naked-eye detection of Cu 2 + ions and was confirmed by spectrophotometric titration. The specific binding mode of dyads as probable with Cu 2 + over other metal ions attributes to the chemoselectivity.

“…In general, these solid-phase sensors consist of a small-molecule fluorescent probe and carriers. Rhodamine is such a probe possessing excellent photophysical properties 5–7 and exhibits chelation-enhanced fluorescence (CHEF), 8–12 whereas polystyrene microspheres as carriers have been widely used in enzyme immobilization, chromatographic separation, and biological sensing because of their large surface area, stable material properties, and surface reaction abilities. 13–15 Chloroacetylated polystyrene microspheres, which are prepared from polystyrene microspheres by Friedel-Crafts acylation, exhibit regular shapes and high chemical resistance, and possess a large number of chloroacetyl groups on the surface to further conduct chemical modifications.…”

Two novel rhodamine-based polystyrene solid-phase fluorescent sensors PS-AC-I and PS-AC-II with different coordination atoms (O or S) are synthesized and shown to be able to detect Hg(II) ions. They are characterized by Fourier-transform infrared spectroscopy and by scanning electron microscopy analysis. Their fluorescent properties, including response time, pH effects, fluorescence titrations, metal ion competition and recycling, are investigated and compared. Sensor PS-AC-II displayed higher selectivity and sensitivity to Hg(II), with a lower detection limit of 0.032 µM, which was 15 times better than PS-AC-I. A detection mechanism involving the Hg(II) chelation-induced ring-opening of the rhodamine spirolactam is proposed with the aid of theoretical calculations.
