MOFs Modified Paper-Based Materials: Preparation and Application to EtOH Fluorescence Response

Based on the solvothermal method, two new MOFs with 3-(1-Oxo-1H-2,3-dihydroisoindol-2-yl)benzoic acid as the organic ligand, Zn-HBPA and Zn-bpy-HBPA were synthesized. The structure of MOFs was characterized by 1H-NMR, XRD, FT-IR and SEM. A series of modified cellulose paper-based functional material...

Summary:Based on the solvothermal method, two new MOFs with 3-(1-Oxo-1H-2,3-dihydroisoindol-2-yl)benzoic acid as the organic ligand, Zn-HBPA and Zn-bpy-HBPA were synthesized. The structure of MOFs was characterized by 1H-NMR, XRD, FT-IR and SEM. A series of modified cellulose paper-based functional materials with different spraying times were prepared by flame spraying method, and the fluorescence property of MOFs modified cellulose paper to EtOH small molecules was investigated by fluorescence spectrometer. The results of FT-IR and SEM showed that the flame spraying method could effectively improve the retention rate of MOFs on cellulose paper materials. The PL characterization results displayed that Zn-HBPA@PFP exhibited a decrease in fluorescence after UV irradiation, while Zn-bpy-HBPA@PFP demenstrated an increase in fluorescence at λ=338 nm. The above results indicated that Zn-bpy-HBPA@PFP had an excellent response ability to EtOH small molecules, and when Cycle=7 times, Zn-bpy-HBPA@PFP had the best fluorescence enhancement effect.
