Poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(bithiophene)]

Описание

Poly(9,9-dioctylfluorene-alt-bithiophene), also known as F8T2, is a semiconducting material that is widely used in organic electronics such as organic photovoltaics, polymer light-emitting diodes (PLED) and organic field-effect transistors (OFETs). Comparing with poly-3-hexylthiophene, F8T2 has even higher mobilities of 0.1 cm2/V·s and relatively higher stability against chemical doping by environmental oxygen or residual impurities such as mobile sulphonic acid in the PEDOT/PSS ink. This enables devices with higher on-off current ratios exceeding 105 and with better operating stability than printed poly-3-hexylthiophene devices.

Использование

F8T2 can be majorly used in the fabrication of active layers for optoelectronics and energy based devices such as organic field effect transistors(OFETs), solar cells, light emitting diodes(LEDs) and electronic gas sensors.

Общее описание

F8T2 is a fluorenated semiconducting polymer which can be used as a hole transporting layer with mobility of 0.02cm²V^-1s^-1. It is highly stable in vacuum and UV based environment. Its liquid crystallinity allows it to form a self-ordered nanostructure on organic thin films.
