Fluorescent probe for carbon monoxide detection and recognition, fluorescent visual test paper based on fluorescent probe, preparation method and application

The invention discloses a fluorescent probe for carbon monoxide detection and recognition, fluorescent visual test paper based on the fluorescent probe, a preparation method and application, and belongs to the technical field of fluorescent probes. The fluorescent probe based on rhodamine B derivative RBF and iron (III) ion complexing is simply and efficiently prepared by utilizing two-step reaction. The fluorescent probe provided by the invention can realize rapid, high-sensitivity, high-selectivity and visual detection and recognition and intracellular fluorescence imaging of carbon monoxide (CO), and the prepared fluorescent visual test paper can realize efficient and visual recognition and detection of CO in air. The problems of single detection mode, difficulty in visual detection, need of expensive palladium (II) salt and the like in the conventional method are solved, and a new thought is provided for the design of CO fluorescent probes and visual test paper with excellent performance. 本发明公开了一种用于一氧化碳检测
