| Outline of Final Research Achievements |
In the field of polymer nanoscience, the relationship between conformation of a conjugated polymer chain and its optical and electrical properties is an important problem both fundamentally and in view of potential applications. Here, we attempted to actively and precisely control the conformation of a single conjugated polymer chain and study its spectroscopic properties and opto-electronic functionality in relation to its conformation. The conformation was controlled by the polymer chain topology resulting from its chemical composition, by incorporation of individual chains into cylinders of phase-separated block copolymers, and by polarity of the surrounding matrix. Using such conformation control, we measured single conjugated polymer chains fluorescence and electroluminescence, and analyzed their photophysical properties in terms of molecular aggregate and charge transfer states, as well as their opto-electronic properties in terms of electroluminescence dynamics.
