The polymer PBTADF was synthesized by the Suzuki coupling reaction. The weight-average molecular of the polymer was determined to be 41202. And the polydispersity indexe obtained by gel permeation chromatography (GPC) using polystyrene standards for calibration in the eluent THF is 1.66. The thermal, optical and electronic properties of the polymer were investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), UV-vis absorption, photoluminescence spectroscopy, cyclic voltammetry. The absorption maximum spectra of the polymer were observed 455 nm in solution state and 347, 520 nm in film state. The PL maximum spectra of the polymer were observed at 561 nm in solution state and 610 nm in film state, respectively. The polymer showed highly thermal stability of decomposition temperature over 400 oC. |
