Abstract: The present disclosure discloses a CO2 quantitative fluorescent sensing material, a preparation method and an application thereof. The preparation method for the CO2 quantitative fluorescent sensing material includes dissolving 9,10-diacrylic anthracene in a solvent to prepare 5-10 mg/mL of a first solution; dissolving MnCl2 or Mn(ClO4)2 in water to prepare 50-100 mg/mL of a second solution; mixing the first solution and the second solution; adding a diluted acid into the mixed solution; sealing and heating the mixed solution. This preparation method is simple. During application, an ionic liquid produced by a reaction of CO2 gas and an amine compound improves an aggregation-induced emission of the CO2 quantitative fluorescent sensing material and a fluorescence thereof is significantly improved. So that a fluorescent CO2 quantification is performed rapidly and accurately.
