| Popis: | A terbium complex [Tb(2,6-dhb)3(H2O)4]·2H2O (1) was directly precipitated when reacting Tb(NO3)3·6H2O with 2,6-dihydroxybenzoic acid (2,6-Hdhb) in the presence of KOH. 1 has been characterized by single-crystal X-ray diffraction, EA, FT-IR, PXRD, TG, SEM, UV–Vis, Fluorescence Microscopy and Photoluminescence spectroscopy. The fluorescence properties indicate that 1 shows typical terbium complex emission both in solid state and in organic solutions, along with a luminescence quantum yield of 26.53% in the solid state, indicative of the presence of a quantitative energy transfer from the ligand to the metal. Furthermore, 1 still emits strong green light even after heating in the oven for half an hour. Biological studies reveal that 87% of Escherichia coli cells and 77% of Staphylococcus aureus cells are killed by the aqueous solution of 1. Taken together, facile synthesis, strong and heat-stable fluorescence and high antibacterial capability make 1 a rather practical bifunctional material, showing promise for anti-counterfeiting and biological applications. |
