Two alternating copolymers containing triphenylamine and biphenyl or fluorene, poly[triphenylamine‐alt‐biphenylene vinylene] (TPA‐PBPV) and poly[triphenylamine‐alt‐2,7‐fluorenenylene vinylene] (TPA‐FLV) were synthesized by means of the Wittig reaction. Both the polymers show good solubility in common organic solvents and excellent film‐forming ability. Thermogravimetric analysis investigation demonstrates that the polymers have high thermal stability, the degradation temperature of TPA‐FLV is as high as 499.0 °C. Differential scanning calorimetry results indicate that the glass transition temperature of poly TPA‐FLV is higher than 200 °C, much higher than that of PBPV‐TPA, which might be a merit for the long‐life operation of light‐emitting devices. The photophysical properties of the polymers were investigated in both CH 2 Cl 2 solution and spin‐coated film, photoluminescence efficiencies are also determined, PFV‐TPA has a higher efficiency, which may make it a more promising candidate for light‐emitting materials.
