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.

Abstract: The present disclosure discloses a reversible continuous variable chromogenic material, a preparation method as well as an application thereof. The present disclosure relates to a field of chromogenic material. The reversible continuous variable chromogenic material crystallizes in a trigonal R3 space group. A fundamental asymmetric unit includes two 9,10-diacrylate anthracene ligands, two Mn2+ and ? ?-O. A plurality of fundamental asymmetric units connect with each other and form a three dimensional infinite network structure. This material is a chromogenic metal-organic framework which performs continuous variable fluorescence color in a wide color gamut. A preparation technology for this reversible continuous variable chromogenic material is facile.
