摘要：

Soluble carbon nanotube ensembles having ferrocene units covalently introduced by 1,3-dipolar cycloaddition of azomethine ylides have been synthesized and studied for light-induced electron transfer interactions. Additionally, supramolecular means have been utilized to immobilize a positively charged water-soluble pyrene derivative to purified single-walled carbon nanotube (SWNT), which was further Coupled by attractive electrostatic interactions to an oligoanionic porphyrin. Electron transfer from the photoexcited states were probed by fluorescence and transient absorption spectroscopy measurements. (c) 2005 Elsevier B.V. All rights reserved.
