| 摘 要： | P-phenylene-2,2‘-bis(5-aminobenzoxazole) is synthesized by the condensation of 2,4-diaminophenol dihydrochloride and terephthalic acid with high yield of 98% in polyphosphoric acid through adding reductive agent SnC12 to suppress the oxidation of 2,4-diaminophenol dihydrochloride. The structure of the compound is characterized by using melting point, FT-IR,^1H NMR, and element analysis.
