研究目的
Developing an effective method for selective and sensitive detection of hypochlorite.
研究成果
The cyclometalated iridium(III) complex (IrCN) serves as an effective 'turn-on' fluorescence probe for hypochlorite detection, offering rapid response, high selectivity, and sensitivity. It has potential applications in real-time monitoring through fluorescent test strips.
研究不足
The probe's performance in highly acidic conditions is limited, and its application in complex biological samples may require further validation.
1：Experimental Design and Method Selection:
The study involved the synthesis and characterization of a cyclometalated iridium(III) complex-based fluorescence probe (IrCN) for hypochlorite detection. The probe's response to hypochlorite was evaluated through fluorescence and UV–vis spectroscopy.
2：Sample Selection and Data Sources:
The probe was tested in CH3CN/H2O solvent (3/7, v/v) with varying concentrations of hypochlorite and other competing species.
3：List of Experimental Equipment and Materials:
Instruments used included a Bruker Avance III for NMR spectra, a Lambda 750 UV–vis spectrophotometer, and a Hitachi F-4600 spectrofluorometer.
4：Experimental Procedures and Operational Workflow:
The probe's fluorescence response to hypochlorite was measured with excitation at 370 nm. Time-dependent response and pH effect studies were conducted.
5：Data Analysis Methods:
The detection limit was calculated based on fluorescence titration experiments, and selectivity was assessed by comparing responses to various analytes.
