Research on vacuum annealing of white-light OLED with polyfluorene copolymer as light-emitting layer
White-light organic light-emitting devices (OLEDs) were fabricated, in which poly(9,9-dioctyl)fluorene with insertion of 4,7-bithienyl-2,l,3-benzothiadiazole (PFO-DBT5) were utilized as light-emitting layer. During fabrication of white-light OLED, PFO-DBT5 films were vacuum annealed under four different temperatures, respectively. Then, the relationship between vacuum annealing of PFO-DBT5 films and performance of white-light OLED was studied by atomic force microscope observation and electroluminescence properties characterization. Finally, it was concluded that degree of stacking order and the inter-chain distance and of PFO-DBT chains influence device performance directly; the optimal vacuum annealing temperature was gained to be 100℃ by comparison experiments.
