Application

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.

General description

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.
Typically soluble in THF, Dichloromethane, or Tolune. (c = 1%, typical appearance may be clear to turbid).
Polymer is end-capped with 3,5-dimethylbenzene.
