Paper Abstract

Fluorene arylene copolymers are a class of aromatic macromolecules that have an alternating backbone structure consisting of a 9,9-dialkylfluorene together with one (or more) additional aromatic group(s). Fluorene when combined with chromophoric and/or charge transporting aromatic monomers to form polyfluorenes have received a great deal of attention over the last several years as the emissive layer in polymeric light emitting diodes. The emission of green, red, or blue light can be controlled by the choice of the aryl backbone segments and alkyl side groups in the polymer. More recently, polyfluorenes have been designed and evaluated as the organic semiconducting layer in polymeric field effect transistors (pFETs). This work has led to a class of polymeric semiconductors with an excellent combination of charge mobility, environmental stability, and processability. These polymers have also been shown to have optoelectronic properties. The high optical density, high charge carrier mobility, and the potential to tune the absorption spectra makes this class of materials an ideal candidate for further study in the area of organic photovoltaics. This paper reviews the synthesis and characterization of polyfluorenes, focusing on the optimization of electronic properties for the conversion of light into electric current.
