Supramolecular fluorescent probe for selectively recognizing norfloxacin as well as preparation and application of supramolecular fluorescent probe

The invention discloses a supramolecular fluorescent probe for selectively recognizing norfloxacin as well as preparation and application of the supramolecular fluorescent probe. The supramolecular fluorescent probe is prepared by taking cucurbit [8] uril and a guest G as raw materials; the specific method comprises the following steps: weighing an object G, and dissolving with water to prepare a solution A; weighing cucurbit [8] uril, and dissolving the cucurbit [8] uril with water to prepare a solution B; and mixing the solution A and the solution B, diluting, and fully shaking up to obtain the supermolecular fluorescent probe for selectively identifying norfloxacin. The supramolecular fluorescent probe can selectively identify norfloxacin in a water system, and has the characteristics of simple preparation, convenient detection, sensitive detection, low detection cost and strong selectivity. 本发明公开了一种选择识别诺氟沙星的超分子荧光探针及其制备和应用。本发明的超分子荧光探针是以八元瓜环和客体G为原料制备而成；具体方法是称取客体G，用水溶解，配制成溶液A；称取八元瓜环，用水溶解，配制成溶液B；将溶液A和溶液B混合、稀释
