Abstract
A series of anthracene-based polymers (P1-3) have been synthesized via the Wittig polycondensation. These organic materials were soluble in common organic solvents and show good film-forming abilities. Their macromolecular structures were characterized by NMR, FT-IR spectroscopies and steric exclusion chromatography, their thermal behaviors were analyzed by differential scanning calorimetry and their HOMO-LUMO energy levels were estimated by cyclic voltammetry. The optical properties of these pi-conjugated systems were investigated by UV-visible absorption and photoluminescence spectroscopies. The effect of the spacer-group structure on the photo-physical behavior, pi-pi stacking ability and charge carrier transport properties of the polymer has been studied.
