摘　　要：将3,4-二氨基苯甲酸与甲酸、羟基乙酸在加热回流的条件下分别反应合成5-羧基苯并咪唑与2-羟甲基-5-羧基苯并咪唑。以硝酸铈铵与过氧化氢为催化剂和氧化剂,使3,4-二氨基苯甲酸与对苯二甲醛在极性非质子溶剂DMF中反应合成1,4-（双5-羧基苯并咪唑）苯。通过熔点测试、IR、1HNMR对所合成的化合物进行结构表征,并通过激发光谱、发射光谱研究了其荧光性能。5-Carboxy-benzimidazole and 2-hydroxymethyl-5-carboxy-benzimidazole were synthesized respectively using 3,4-diaminobenzoic acid and formic acid（ glycolic acid） as the reactants under reflux conditions.In polar aprotic solvent DMF,1,4-bis（ 5-carboxy-benzimidazole） benzene was synthesized with 3,4-diaminobenzoic acid and terephthalic aldehyde as reactants,hydrogen peroxide asoxidant and ammonium cerium nitrate as catalyst. The structures of the compounds were confirmed by melting point test,IR and1 HNMR.And the fluorescent properties were investigated by excitation and emission spectra.
