✦ Synopsis

Fullerenes and, more recently, carbon nanotubes (CNTs) have emerged as an innovative and new class of nanoscale carbon-based materials that are currently under intensive investigation. [1] The excitement in this area is, by large, a consequence of their promising functions in molecular-scale electronic applications. In stark contrast to the wealth of [60]fullerene-based donor-acceptor dyads studied so far, [2] the incorporation of single-walled carbon nanotubes (SWNTs) into donor-acceptor ensembles has been scarcely explored, and only a few examples involving the covalent linkage of electroactive species are known. [3] For example, some of us reported the functionalization of SWNTs with electron-donating ferrocene and confirmed that in this particular case electron transfer occurred from the ferrocene to the photoexcited SWNT. This initial work stimulated the use of SWNT nanoconjugates in solar energy conversion applications. [4] However, control over the electron transfer in SWNTs remains a central but unsolved topic.
