properties of nine newcompounds based on phthalimides, isoindolin-1-ones and isoindolines bearing aminobenzoic acids (2-aminobenzoic acid, 3-aminobenzoic acid and 4-aminobenzoic acid), which were obtained under mild reaction conditions. The photophysical properties of all the compounds were studied by electronic absorption and fluorescence spectroscopy in methanol solutions. All compounds exhibited fluorescence
2-, 3-, and 4-(1-Oxo-1H-2,3-dihydroisoindol-2-yl)benzoic acids and their corresponding organotin carboxylates: Synthesis, characterization, fluorescent, and biological activities
Three novel organotin complexes with general formula Sn(OH)(bz)(2)L (bz = benzyl, HL = 2-, 3-, or 4-(1-oxo-1H-2,3-dihydroisoindol-2-yl)benzoic acid) and one of their ligands were prepared and characterized. In vitro antifungal and antibacterial activities of these complexes and ligands were investigated with the representative strains of Candida albicans, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Their fluorescence properties have also been discussed. (C) 2010 Elsevier Ltd. All rights reserved.

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.
