| Abstract: | A series of terbium complexes with salicylhydrazide–salicylacylhydrazone derivatives were synthesized and characterized by elemental analysis, IR spectra, UV/vis spectra and thermal analysis. The luminescence and electrochemical properties of the terbium complexes were investigated. The results show that all the target complexes exhibited characteristic emissions of terbium ions and the complex substituted by the chlorine has the strongest luminescence intensity with the highest quantum yield at 0.609. The introduction of donating electron groups could increase the oxidation potential and the highest occupied molecular orbital energy level of the terbium complex; however, the introduction of accepting electron groups gave the opposite result.
