At typical concentrations of 10 mg/ml, 100 mg of F8 (PFO) will make around 200 devices on Ossila''s standard ITO substrates (20 x 15 mm), assuming 50% solution usage (50% loss in filtering and preparation). | [Description]
Poly(9,9-di-n-octylfluorenyl-2,7-diyl), known as F8 or PFO, is a polyfluorene specifically optimised for a variety of organic electronic applications. |

| [Applications]
For a high-efficiency green OLED we recommend blending F8 with F8BT with the below specifications. This ink can then be applied either in air, or in a glovebox, with little difference in performance (provided exposure time and light levels are minimised).
At typical concentrations of 10 mg/ml, 100 mg of F8 (PFO) will make around 200 devices on Ossila's standard ITO substrates (20 x 15 mm), assuming 50% solution usage (50% loss in filtering and preparation).
OLED reference device:
- F8 with F8BT
- Blend ratio of 19:1 (F8:F8BT) in Toluene
- Total concentration of 10 mg/ml
- 0.45 μm PTFE filter
- Spun at 2000 rpm (approx. 70 nm thickness)
Pipetting 20 μl of the above solutions onto a substrate spinning at 2000 rpm should provide a good even coverage, with approximately 70 nm thickness. The substrate needs to be spun until dry, which is typically only a few seconds — 15 seconds should be ample to achieve this. Thermal annealing should be undertaken at 80°C for 10 minutes prior to cathode deposition.
