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(1H NMR,13C NMR,DEPT,1H-1H COSY,HMQC,HMBC)对该化合物进行了结构表征,准确归属了它们的1H,13C信号,为其结构鉴定提供了重要依据.

Abstract:

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 Suzuki 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.

Key words: NMR, assignment, 2D NMR, polyfluorene derivatives
