| Research Abstract |
Photophysical processes occurring within optoelectronic materials play a crucial role in designing optoelectronic devices. It has been impossible to visualize the photophysical processes directly since these processes generally occur in a spatial size of nanometers to tens of nanometer which cannot be resolved by conventional optical microscopy technique. In this study, we developed a new fluorescence microscopy technique which has a nanometer spatial resolution. Using the technique, we visualized nano-scale exciton migration and localization in conjugated polymer molecules. We demonstrated that the exciton can migrate along the polymer chains up to 70nm, which is much longer than previously expected distances.
