A new oligomeric fluorophore, which combines the advantage of polycyclic aromatic compounds and fluorene structures has been synthesized. The new compound shows necessary film-forming properties, is readily soluble in the majority of organic solvents and emits in the blue range of solar light with maximum at 465 nm. The compound has a rather high quantum yield and can serve as both the electroluminescent dopant and the conducting light-emitting matrix for designing completely soluble blue and white OLEDs by both inkjet printing and spin coating. The new oligomeric fluorophore is a promising example of highly fluorescent oligomer, rarely used class of materials, in contrast to polymers and small molecules. Such oligomers can be useful for future completely soluble OLEDs.

7'-[7,10-双-(4'-氟苯基)荧蒽-8-基](9,9-二癸基)芴的合成、光致发光和电致发光特性作为蓝色有机发光二极管的有前途的材料

合成了一种新的寡聚荧光团，它结合了多环芳族化合物和芴结构的优点。这种新化合物显示出必要的成膜性能，易溶于大多数有机溶剂，并在太阳光的蓝色范围内发射，最大波长为 465 nm。该化合物具有相当高的量子产率，可作为电致发光掺杂剂和导电发光基质，用于通过喷墨印刷和旋涂设计完全可溶的蓝色和白色 OLED。与聚合物和小分子相比，新的低聚荧光团是高荧光低聚物的一个有前途的例子，是很少使用的一类材料。这种低聚物可用于未来的完全可溶性 OLED。
