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

17_07/2005The 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.
