双二氮杂萘酮类化合物的电喷雾质谱研究

Study of Bis(diazonaphthenone) Compounds by ESI - MS^n

含新型芳香杂环单元的缩聚高分子材料耐老化热稳定性好[1,2],具有独特的加工长度和弹性模量[3],在宇航、电子、机械、军事和复合材料等方面的应用已引起人们的广泛兴趣和关注.含双二氮杂萘酮单元的缩聚高分子材料就是其中一种,这些新型芳香杂环单元大多数熔点都较高,难于汽化,采用电子轰击质谱或快原子轰击质谱测定其相对分子质量时,通常得不到分子离子峰信号,给质谱表征和结构鉴定带来一定的困难.……

Five novel bis (diazonaphthenone) compounds has been studied by electrospray ionization multiple stage mass spectrometry. A proposed fragmentation scheme has also been summarized.
