An amphiphilic diblock-copolymer consisting of poly(3-hexylthiophene) and poly(4-vinylpyridine) has been synthesized and self-assembled from mixed selective solvents of tetrahydrofuran and methanol to produce nanostructures having photoluminescence spanning from the blue to the red. The emission decay times of the nanostructures have been found to increase with the fraction of methanol, suggesting...
Poly(3-hexylthiophene)-coated gold (Au@P3HT) hybrid nanoparticles have been prepared via a “grafting-to” approach, and compared with pristine P3HT to investigate the dynamics of exciton relaxation using time-resolved transient-absorption and fluorescence spectroscopy. In efforts to facilitate the efficient dissociation of photo-generated excitons, we have incorporated gold nanoparticles having surface-plasmon...
