A practical material based on 2,6-dihydroxybenzoic acid: Facile synthesis, strong fluorescence and high-efficiency antibacterial performance

A practical material [Tb(2,6-dhb)3(H2O)4]·2H2O (1), prepared by a facile, economical and environment-friendly method, has been characterized by single-crystal X-ray diffraction, EA, FT-IR, PXRD, TG, SEM and UV-Vis. 1 shows strong and heat-stable fluorescence with the luminescence quantum yield of 26.53%. Biological studies reveal that 87% of Escherichia coli cells and 77% of Staphylococcus aureus cells have been killed by the aqueous solution of 1.110
