| Outline of Final Research Achievements |
In this project, we studied the following three issues. First, we studied the exciton dynamics in J-aggregated crystalline conjugated polymer PNOz4T films. As a result, we found that two-dimensional exciton diffusion is dominant at room temperature and one-dimensional exciton diffusion is dominant at lower temperatures. Second, we studied the exciton dynamics in highly crystalline J-aggregated conjugated polymer P3HT films. As a result, we found that singlet excitons exhibit rapid radiative and non-radiative rate ~100 time faster than those for H-aggregated normal P3HT films. Third, we studied singlet fission in crystalline conjugated polymer PDPP3T films. As a result, we found that singlet fission more efficiently proceeds in H-aggregated films rather than in J-aggregated films.
