Description générale

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.

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.

High-Performance Semiconductor Polymers Based on Diketopyrrolopyrrole and Thienothiophene

The development of high-performance conjugated organic molecules and polymers has received widespread attention in industrial and academic research.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Flexible Organic Transistors for Biomedical Applications

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.
