Abstract (Summary)

This work’s focus was set on (6,5)-SWNT-PFO-BPy complexes as representatives for polyfluorene-stabilized single-wall carbon nanotubes. As a first project, preparative methods for dispersion and deposition of these samples were refined. The batch size was successfully scaled up from 15 mL to 200 mL and thin SWNT-films were prepared by spin coating.

Furthermore, light-induced dynamics from the ps to the µs time scale were investigated in semiconducting SWNTs. Here, a comprehensive picture of the singlet and triplet exciton dynamics in semiconducting SWNTs was provided, which is significantly affected by diffusion-limited processes.

Finally, a method providing information about the structure of SWNT-polymer complexes and other supramolecular system was introduced. It is based on a combination of polarization angle-resolved absorption spectroscopy of anisotropic samples and global data analysis.
