Interplay of physical structure and photophysics for a liquid crystalline polyfluorene

Abstract

Certain treatment protocols have been found to cause dramatic changes in the absorption spectra of poly(9,9-dioctylfluorene). Based on petrophysical evidence, a structural model based on intrachain ordering is suggested that can account for these spectroscopic phenomena in PFO films. The model is correlated to X-ray fiber diffraction observations.
