POLY(9 9-DI-N-OCTYLFLUORENYL-2 7-DIYL)

Classification

Polyfluorenes, Benzothiodiazoles, Organic semiconducting materials, Semiconducting polymers, OLED green emitter materials, OLED materials, Organic Photovoltaic materials, Polymer solar Cells, OFET materials.

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)

Application

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.
