MS Analysis on Intermediate during the Synthesis of Fluorene-based Electroluminescent Materials

本文报导了新化合物 2 ,7-双 ( 4,4 ,5 ,5 -四甲基 -1 ,3 ,2二氧杂硼烷 -二基 ) -9,9-二辛基芴的 EI和 ESI的质谱 ,利用质谱 -质谱 ( MS/ MS)分析 ,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 spectrograph of a novel compound, 2,7-bis (4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-9,9-dioctylfluorene is reported. Relationship between the daughter ions and the parent ion was verified by tandem mass spectrometry (MS-MS) analysis and the fragmental route is discussed. This provides a firm base for its structure identification.
