| Outline of Final Research Achievements |
In this study, we succeeded in synthesizing defect-free cyclic poly(3-hexylthiophene) (P3HT) with the aim of constructing an ideal cyclic all-π-conjugated structure and analyzed the exciton state from the fluorescence and absorption properties in solution.
It was also shown that the physisorption of cyclic poly(ethylene glycol) (PEG) drastically improves the dispersion stability of gold nanoparticles. This method outperformed the chemisorption of the most commonly used thiol-terminated PEG, and the dispersion stability was maintained even when the gold nanoparticle dispersion was subjected to freezing, lyophilization, heating, and physiological conditions.
