Five bis-1,2,4-triazine derivatives were synthesized by the reaction of benzil, dihydrazide and ammonium acetate in acetic acid under microwave irradiation with yields of 72%~85%. The structures of the title compounds were characterized by elemental analysis, IR, 1H NMR, MS and fluorescence spectra. The effect of metal ions on fluorescence characterization of compound 3a was investigated. The microwave irradiation dramatically shortened the reaction times, affording the desired products in high yields. The selective interaction between metal ions (Cu2+, Ni2+) and 3a led to obvious fluorescence quenching.

Key words: fluorescence characterization, fluorescence quenching, microwave-assisted synthesis, ion recognition, 1,2,4-triazine
