摘　　要：用激光解吸质谱法（ＭＡＬＤ）和快原子轰击（ＦＡＢ）质谱法分别研究Ａｌ－酞青和Ｃｕ，Ｎｉ，Ｚｎ４，４＇，４″，４－四羧基酞青化合物。四羧基取代酞青由于四个羧基取代导致酞青极性增大和挥发点增高，较难于用ＦＡＢ法测定，但用基体帮助激光解吸质谱法可得到满意的结果，而一般铝酞青化合物分别用ＦＡＢ和ＭＡＬＤ法都可获得满意结果，但ＦＡＢ法能获得更多碎片信息。Al-phthalocyanine and Cu,Ni,Zn 4,4',4″,4-tetracarboxyl phthalocyanines have been studied by laser desorption(MALD)and fast atom bombardment(FAB)mass spectrometry,The carboxyl and metalderivatives are less volatile than unsubstituted ones,and cannot be determined by FAB but they can be determined by laser desorption method with good results;Al-derivatives can be determined by both FAB andMALD with promising results but more fragment informations can be obtained by FAB method.
