Abstract
Three kinds of PPV-based copolymers were synthesized and characterized . Their luminescent properties were investigated and discussed by PL s pectrum, and time-dependence luminescent spectrum in film and solution stare. The results show that in the range of our study, the PL intens ity and lifetime of luminescent decay increase with the increasing len gth of flexible segments and the solution diluting, indicating the ten dency of the increase of luminescent efficiency.
