Single-Wall Carbon Nanotube-Ferrocene Nanohybrids: Observing Intramolecular Electron Transfer in Functionalized SWNTs

摘要

Since their discovery, carbon single-wall nanotubes (SWNTs) have drawn considerable attention, not only due to their unique chemical and physical properties, but also because of their promise in the area of materials chemistry. A central aspect of nanotube chemistry, which yet awaits exploration, is their functionality and performance in donor-acceptor ensembles. Our recent success in SWNT functionalization, based on the 1, 3-dipolar cycloaddition of azomethine ylides to the double bonds of SWNTs, led us to pursue the covalent linkage of an electron donor, namely ferrocene, to the allcarbon network. Here we report for the first time on intramolecular electron transfer reactions in a novel SWNT-based donor-acceptor ensemble.
