摘要
From photophysical evidence, we suggest a structural model based on intrachain ordering that can account for the thermoreversible changes of the absorption spectrum of poly(9,9-dioctylfluorene) films under certain physicochemical treatment protocols. We correlate this model to the results of X-ray fibre diffraction experiments. (C) 2000 Elsevier Science S.A. All rights reserved.
