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
