Double advantages of Benzimidazolyl‑hydroxy-coumarinyl diad - “turn-on” sensing of Al3+ and preventing metastasis in cancer

Two rhodamine-azo based fluorescent probes for recognition of trivalent metal ions: crystal structure elucidation and biological applications

“…Some recently reported rhodamine-based chemosensors are given in Chart S1 24 (ESI †). A literature survey on previously reported rhodamine based chemosensors [24][25][26] (both single metal ion and multiple metal ion detectors) and other chemosensors [27][28][29][30] (both single metal ion and multiple metal ion sensors) reveals that our reported chemosensors, which simultaneously detect three trivalent metal ions, have certain advantages like easy synthetic procedures involving less expensive chemicals, a high fluorescence enhancement in the presence of metal ions, low LOD values (10 −9 M order), dual sensing character (colorimetric and fluorescence), X-ray structures of both free chemosensors and their metal bound forms and real world and biological applications. One main drawback of these chemosensors is their partial solubility in an aqueous medium.…”
