聚芴类发光材料合成中间体的质谱分析

MS Analysis on Intermediate of Synthetic Polyfluorene Electroluminescent Materials

利用电喷雾电离(ESI)质谱 -质谱 (MS -MS)技术 ,分析了新化合物2,7_双 (4,4,5,5_四甲基_1,3,2二氧杂硼烷_2_基 )_9,9_二辛基芴的EI和ESI的质谱 ,确认了该谱图中母离子和子离子的关系 ,讨论了其碎裂途径 。

EI and ESI mass spectrograms of a novel compound, 2,7 _ bis(4,4,5,5 _ tetramethyl _ 1, 3, 2 _ dioxa_borane _ 2 _ yl) _ 9,9 _ dioctylfluorene(BTDF) is reported. Relationship between the daughter ions and the parent ion was verified by tandem mass spectrometric(MS-MS) analysis and the fragmentation pathways of BTDF under EI _ MS and ESI _ MS conditions were discussed. This provided a firm base for its structure identification.
