Novel photoactive single-walled carbon nanotube-porphyrin polymer wraps: Efficient and long-lived intracomplex charge separation
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.
