Low band gap π-conjugated polymers composed of phenothiazine, bithiophene, and perylene moieties were prepared in high yields by palladium-catalyzed Suzuki coupling reaction. The polymers were characterized by NMR, gel permeation chromatog., and elemental anal. The characterizations revealed that high-mol. weight (weight-average mol. weight up to 42 400 g/mol) polymers were thermally stable with a decomposition temperature at 338-354° and glass transition temperature (Tg) 124-136°. All polymers demonstrated broad optical absorption in the region of 300-550 nm with efficient blue-green light emission. The absorption was broadened further (for ca. 50 nm) when the perylene moiety was incorporated. Cyclic voltammograms displayed that the p- and n-doping processes of all the polymers were partially reversible and that electrochem. band gaps were as low as -2.30 eV with the incorporation of a perylene moiety. The hole mobility of polymers was evaluated by using the space-charge-limited current model with a PLED device structure of ITO/PEDOT:PSS/polymer/Ca. The incorporation of perylene is beneficial for improving the hole mobility of the conjugated polymers.
