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.
