摘要：A new blue-light emitting polymer poly[5-(diphenylamino)-1,3- phenylenevinylene] (Yu1) was synthesized by McMurry condensation reaction of 5-(N,N-diphenylamino)benzene-1,3-dicarbaldehyde (Yu0) in the presence of zinc dust and TiCl4. The polymer displayed good thermal stability and highly solubility in common organic solvents. This polymer exhibited a strong blue emission around 455 nm with a fluorescence lifetime of 7.12 ns in Ar-saturated toluene. Photoinduced intermolecular electron transfer process of C60/Yu1 system was also examined by steady-state, time-resolved, and nano-second transient absorption techniques. It was observed that the electron transfer process from Yu1 to C60 was more efficient than that for Yu0 to C60. The efficiencies of the electron transfer process were evaluated as 0.07 and 0.76 for 3C60/Yu0 and 3C60/Yu1, respectively.
