摘要
通过Suzuki偶联聚合反应得到D-A-D型聚芴衍生物的关键中间体2,7-二(4,4,5,5-四甲基-1,3,2-二氧杂硼烷-2-基)-9,9-二辛基芴.应用一维和二维核磁共振技术(1 H NMR,13 C NMR,DEPT,1 H-1 H COSY,HMQC,HMBC)对该化合物进行了结构表征,准确归属了它们的1 H,13 C信号,为其结构鉴定提供了重要依据.
An important intermediate of D-A-D polyfluorene derivative, 2,7-bis （4,4,5, 5-tetramethyl-1,3,2-dioxaboralan-2-yl）-9,9-dioctylfluorene, was synthesized from Su- zuki coupling polymerization. One- and two-dimensional NMR techniques （i. e. , ^1H NMR, ^13C NMR, DEPT, ^1H-^1H COSY, HMQC and HMBC） were used to assign the proton and carbon chemical shifts and to elucidate the structure of the compound.
