Synthesis, Photo- and Electroluminescent Properties of 7'-[7,10-Bis-(4'-fluorophenyl)fluoranthen-8-yl](9,9-didecyl)fluorene as a Promising Material for Blue Organic Light-Emitting Diodes

摘要

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.
