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

Filled Carbon Nanotubes: (X@CNTs)

“…Such a consistency is claimed for Agor CrO 3 -filled SWCNTs, whose modelling confirms to the donor and acceptor roles, respectively, of the filling materials toward the containing SWCNTs in agreement with the resonant Raman data [32]. Electron transfer was also found in bulk ferrocene@SWCNT material upon photoexcitation [105]. However, the recent work by Carter et al [27] can be considered the first full demonstration of the modification of the electronic behaviour (namely, the change from semimetal to semiconductor) from the geometric constrains imposed on the encapsulated crystal in a HgTe@SWNT material.…”

“…Although fullerenoids are the most popular filling molecules, several other organic molecules have been recently inserted in SWCNTs, including metallocenes [4,5,12,96,[105][106][107][108], octasiloxane [6], ortho-carborane and related molecules [2,3], fulvalenes [109], Zn-diphenylporphyrin [1,110], Pt-porphyrin, rhodamin-6G, and chlorophyll [110], and squarylium dye [7].…”

Donor–acceptor nanoensembles of soluble carbon nanotubes

“…1,2 The development of SWNT-based photovoltaic hybrids as potent alternatives to inorganic semiconducting materials has, however, drawn much less attention. 3 Here we present the coulomb complex formation of a water-soluble SWNT grafted with poly(sodium 4-styrenesulfonate) (SWNT-PSS, Fig. 1) and an octapyridinium free base porphyrin salt H 2 P 81 en route to versatile donor-acceptor ensembles and the proof for an intra-ensemble charge separation in SWNT-PSS n2 /H 2 P 81 that lives tens of microseconds.…”

Single‐Walled Carbon Nanotubes Tethered with Porphyrins: Synthesis and Photophysical Properties

“…[10] Nakashima and coworkers complexed porphyrins with SWNTs via non-covalent interactions and investigated the photophysical properties of the resulting materials. [11] Porphyrins are often used as visible chromophores to decorate the surface of semiconductor and metal nanoparticles.…”
