摘要：

Ligands of 3-benzoyl-2-heptylchroman-4-one (L1), and 3-benzoyl-2-phenylchroman-4-one (L2) were synthesized. Two complexes were synthesized via the reaction of L1 and L2 as the first ligand and water as the second ligand with EuCl3 in alcohol solution (pH = 7-8). The related substances were characterized by elemental analysis, infrared spectroscopy, fluorescence spectroscopy, thermogravimetric analysis and scanning electron microscopy. The results show that the composition of two complexes is Eu(L1)3•2H2O and Eu(L2)3•2H2O, respectively. It is indicated that these two complexes can emit the intense characteristic fluorescence of europium ions, in which the fluorescent intensity of the complexes of Eu(L2)3•2H2O is more intense, and has better fluorescent properties. © 2019, Editorial Department of Journal of the Chinese Ceramic Society.
