Effect of polymer chain structure and chain distance on luminescent efficiency

By Hong ZY, Zhao XJ, Ma DG, Wang DK, Jing XB and Wang FS

Abstract

Three kinds of PPV-based copolymers were synthesized and characterized. Their luminescent properties were investigated and discussed by PL spectrum, and time-dependence luminescent spectrum in film and solution stare. The results show that in the range of our study, the PL intensity and lifetime of luminescent decay increase with the increasing length of flexible segments and the solution diluting, indicating the tendency of the increase of luminescent efficiency
