Usage

Description

POLY(9,9-DI-N-OCTYLFLUORENYL-2,7-DIYL), also known as F8 or PFO, is a polyfluorene specifically optimized for a variety of organic electronic applications, particularly in the field of high-efficiency green OLEDs.

Uses

Used in Organic Electronic Applications:
POLY(9,9-DI-N-OCTYLFLUORENYL-2,7-DIYL) is used as a key component in the development of high-efficiency green OLEDs for various electronic devices.
Used in OLED Manufacturing:
OLED Reference Device:
For the creation of an OLED reference device, the F8 and F8BT blend is filtered through a 0.45 μm PTFE filter and spun at 2000 rpm, resulting in an approximate 70 nm thickness. The substrate is then spun until dry, typically within a few seconds to 15 seconds. Thermal annealing is performed at 80°C for 10 minutes before cathode deposition.
Efficiency and Device Production:
At a typical concentration of 10 mg/ml, 100 mg of F8 (PFO) can be used to create around 200 devices on Ossila's standard ITO substrates (20 x 15 mm), assuming a 50% solution usage (50% loss in filtering and preparation).
