摘要
Copolymers of 1,1‘-binaphthyl and oligothiophenes have been synthesized by using the Suzuki coupling reaction. These polymers are soluble in organic solvents such as chloroform and THF. The higher molecular weight polymers have shown high thermal stability. These binaphthyl−thiophene copolymers have well-defined conjugation that is independent of their polymer chain length. With the increase of the number of thiophene units in the repeating unit, both the absorption and emission wavelengths of these polymers undergo a red shift. Materials that can emit different intense colors have been obtained. This study demonstrates that the luminescence properties of binaphthyl-based conjugated polymers can be systematically tuned.
