| Abstract: | A novel method to synthesize 2,6-bis(p-aminophenyl)benzo\1,2-d;5,4-d'\]bisoxazole using 1,2,3-trichlorobenzene as the starting material through nitration, substitution, hydrogenation, and condensation was reported. During the condensation, the influence of the amount of SnCl_2 on the yield of the product was studied. The electron spectra of the compound were discussed, the results showed that it is a fluorescence material with large Stokes shift. |
