Abstract
Energy transfer mechanism is a big topic on opto-electrophysics, especially in conjugated conducting polymers. The conducting polymer exhibits good optoelectric properties, which are worthy of research and commercial values. People, therefore, have done their efforts on studies to unveil the secrets and unknowns of the energy transfer mechanism. In this thesis, the short chain MEH-PPV polymer is studied. By using the time-correlated single photon counting technique for the time-resolved spectroscopic measurement and the spectrum shift study, we can find that the energy transfer is efficient and the direction is from smaller to larger chromophores. A simple polymer chain model for our short chain polymer is also proposed and found to be consistent with the experimental data.
