Highly conjugated 4ThFlu and 4ThNa copolymers were synthesized by the Suzuki coupling reaction. the copolymers were easy to be soluble in common solvents (THF, CHCl3, Toluene etc) due to the introduction of long alky chains.The weight-average molecular weight of the 4ThFlu and 4ThNa copolymer were determined to be 16848 and 13505, respectively. And the polydispersity indexes obtained by gel permeation chromatography (GPC) using polystyrene standards for calibration in the eluent THF is 1.55 and 1.59, respectively. The thermal, optical and electronic properties of copolymers were investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), UV-vis absorption, photoluminescence spectroscopies, cyclic voltammetry. The copolymers were showed highly thermal stability of decomposition temperature over 300 oC |
