•A novel hydrazone ligand based on quinoline was designed and synthesized.•The reason for no characteristic fluorescence of Sm(III) complex was discussed.•A novel ternary Sm(III) complex was synthesized by introducing 1,10-phenanthrolin.•The ternary complex showed efficient luminescence through an energy-transfer pathway.
A novel ligand called 2-oxo-quinoline-3-carbaldehyde-isonicotinyl hydrazone (L) was designed and synthesized, and its Sm(III) complex was successfully prepared and characterized by X-ray diffraction. According to investigation, the Sm(III) complex didn’t exhibit characteristic fluorescence due to the mismatching energy between L and Sm(III) ion. However, when the complex was reacted with 1,10-phenanthrolin (Phen) as a secondary ligand, a novel ternary Sm(III) complex was synthesized, which showed efficient luminescence activity through an energy-transfer pathway. These results indicated that 1,10-phenanthrolin was an excellent sensitizer to Sm(III) ion.
