Abstract:A new organic ligand: 1,4-bis(3,5-dimethyl-1H-pyrazol-1-yl) phthalazine had been synthesized by 1,4-bihydrazine-phthalazine and pentane-2,4-dio-ne through the microwave reaction and the normal reaction in ring closure reaction, and its chemical structures was characterized by IR, 1H NMR and MS. The liquid fluorescence characteristics of the Eu^3+ , Td^3+ complexes were studied in different solvents (methanol, ethanol, 1,4-dioxine) respectively.
Keywords:1  4-bis(3  5-dimethyl-1H-pyrazol-1-yl) phthalazine  synthesis  liquid fluorescence
