PFO (F8)

Semiconducting Polymer for High Efficiency Green OLEDs Optimized for a variety of organic electronic applications Overview | Specifications | MSDS Poly(9,9-di-n-octylfluorenyl-2,7-diyl), known as F8 or PFO, is a polyfluorene specifically optimized for a variety of organic electronic 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 glove box, with little difference in performance (provided exposure time and light levels are minimized). 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). Luminosyn™ PFO (F8) Luminosyn™ PFO (F8) is now available.

When used with the Ossila ITO glass OLED substrates and shadow masks this produces an easy to fabricate yet efficient >100 cd/m2 device. Typical Ossila device architecture: Polyfluorene-based OLED architecture based on F8 blended with F8BT. 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 (hydrophobic) 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.
