A family of linear oligofluorene-BODIPY structures, containing either a ter- or quaterfluorene unit, have been prepared, in which the attachment of the oligofluorene chain to the BODIPY unit is switched between the meso- and beta-positions. Each member of this family was investigated by UV-vis absorption and photoluminescence spectroscopy, cyclic voltammetry and thermal studies (TGA and DSC) to determine their suitability as emissive layers in hybrid luminescent devices. One candidate was then successfully deployed as a down converter to convert UV to visible light.
我们制备了一系列含有三

芴-BODIPY 结构,在这些结构中,低聚
芴链与 BODIPY 单元的连接在介位和 beta 位之间切换。通过紫外-可见吸收和光致发光光谱、循环伏安法和热学研究(TGA 和
DSC)对该系列的每个成员进行了研究,以确定它们是否适合用作混合发光器件中的发射层。其中一种候选材料被成功地用作下转换器,将紫外光转换为可见光。
