Coumarin Derived “Turn on” Fluorescent Sensor for Selective Detection of Cadmium (II) Ion: Spectroscopic Studies and Validation of Sensing Mechanism by DFT Calculations
A highly selective and sensitive fluorescent sensor for the detection of hydrazine has been developed. It can trace hydrazine changes in live cells and live fish. The sensing mechanism is well rationalized with the aid of TD-DFT calculations.
A novel fluorescent sensor, 1O, based on photochromic diarylethene with a 2-hydroxybenzhydrazide unit was designed and synthesized and can be used to recognize Al3+ in methanol (2.0 × 10−5 mol L−1).
A new fluorescent sensor 5 having fused imidazopyridine scaffold has been synthesized via cascade cyclization. It exhibits highly sensitive and selective detection of Fe3+ (‘turn-on’) and Hg2+ (‘turn-off’) in vitro and in HeLa cells.
A turn-on fluorescent sensor based on benzothiadiazole was constructed for simultaneous selective and visual detection of oxalyl chloride and phosgene.
