Cover Picture: Novel Photoactive Single-Walled Carbon Nanotube-Porphyrin Polymer Wraps: Efficient and Long-Lived Intracomplex Charge Separation (Adv. Mater. 7/2005)

The figure on the cover portrays a novel donor–acceptor nanoassembly, based on a single‐walled carbon nanotube (SWNT) as the electron acceptor and poly(methyl methacrylate) (PMMA)‐carrying porphyrin units (H2P) as the excited‐state electron donors. In these supramolecular “polymer wraps”, reported on p. 871 by Guldi and co‐workers, SWNTs quench the photoexcited H2P chromophores, resulting in the creation of microsecond‐lived radical ion pairs. Novel donor‐acceptor nanoassemblies (see cover) are prepared using pristine single‐walled carbon nanotubes (SWNTs) as electron‐acceptor components in supramolecular “polymer wraps”, with poly(methyl methacrylate) carrying porphyrin units (H2P) as excited‐state electron donors (see Figure). In these novel donor–acceptor ensembles, SWNTs quench the photoexcited H2P chromophores, resulting in the creation of long‐lived radical ion pairs.
