| Functionalized single-walled carbon nanotubes possessing photoactive units have been prepared, analytically characterized and morphologically visualized. The characteristic electron donor has been realized either by covalent attachment onto the sidewalls of SWNTs or alternatively by supramolecular van-der-Waals / electrostatic interactions giving rise to diverse hybrid systems. Intramolecular electron transfer processes within these nanohybrids were probed by fluorescence and transient absorption spectroscopy. |
