摘　　要：Two conjugated polymers HXS-1 and PDFCDTBT were prepared by direct C–H activation and Suzuki polycondensation and their chemical structures were characterized by 1H NMR spectroscopy.The molecular weight of conjugated polymer synthesized by direct C–H activation is lower than the corresponding polymers prepared by Suzuki polycondensation.Conjugated polymers synthesized by direct C–H activation have considerable solubility in common organic solvents and form amorphous film.The photovoltaic property of conjugated polymers synthesized by direct C–H activation is inferior to the corresponding polymers synthesized by Suzuki polycondensation.Two conjugated polymers HXS-1 and PDFCDTBT were prepared by direct C-H activation and Suzuki polycondensation and their chemical structures were characterized by 1^H NMR spectroscopy. The molecular weight of conjugated polymer synthe- sized by direct C-H activation is lower than the corresponding polymers prepared by Suzuki polycondensation. Conjugated polymers synthesized by direct C-H activation have considerable solubility in common organic solvents and form amorphous film. The photovoltaic property of conjugated polymers synthesized by direct C-H activation is inferior to the corresponding polymers synthesized by Suzuki polycondensation.
