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 (H 2 P) as excited‐state electron donors (see Figure). In these novel donor–acceptor ensembles, SWNTs quench the photoexcited H 2 P chromophores, resulting in the creation of long‐lived radical ion pairs.
