General description

F8BT is a fluorene copolymer that is used as a light-emitting polymer (LEP) with low energy of lowest unoccupied molecular orbital (LUMO), high electron mobility and luminance.

Application

F8BT can be used with poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PTO) to map the effect of noise sources on photoconducting charge transports by evaluating the conductivity and noise source density (Nt). It may also form a nanocomposite with single walled carbon nanotube (SWCNT) with excellent electric properties and high Seebeck coefficient, for potential application in the development of photovoltaic power and biomass energy. Organic light emitting diode (OLED) devices can be fabricated by depositing a blend of F8 and F8BT on PEDOT:PSS films.

Materials Design Concepts for Efficient Blue OLEDs: A Joint Theoretical and Experimental Study

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
