“…217,461,462 The shift in Fermi energy from this approach is mild in comparison to CCNs and is typically introduced for use in electronic and catalytic applications. Heteroatom doping in graphitic systems is typically limited to a few atom percent; however, other specific phases are known.…”

Since the discovery of buckminsterfullerene over 30 years ago, sp 2 -hybridised carbon nanomaterials (including fullerenes, carbon nanotubes, and graphene) have stimulated new science and technology across a huge range of fields. Despite the impressive intrinsic properties, challenges in processing and chemical modification continue to hinder applications. Charged carbon nanomaterials (CCNs), formed via the reduction or oxidation of these carbon nanomaterials, facilitate dissolution, purification, separation, chemical modification, and assembly. This approach provides a compelling alternative to traditional damaging and restrictive liquid phase exfoliation routes. The broad chemistry of CCNs not only provides a versatile and potent means to modify the properties of the parent nanomaterial but also raises interesting scientific issues. This review focuses on the fundamental structural forms: buckminsterfullerene, single-walled carbon nanotubes, and single-layer graphene, describing the generation of their respective charged nanocarbon species, their interactions with solvents, chemical reactivity, specific (opto)electronic properties, and emerging applications.

“…Despite the fact that many works reported the Raman spectroscopy studies on SWCNTs filled with electron acceptors and common doping‐induced trends in changing Raman modes were revealed, there are only a few reports on the Raman spectroscopy studies of SWCNTs filled with electron donors using a limited number of laser wavelengths. In Refs.…”

“…The filling of SWCNTs has been shown to be a promising method for the directional modification of the electronic structure of SWCNTs. [9][10][11] The SWCNTs can be filled with different simple substances, [12][13][14] chemical compounds, [15][16][17] and molecules [18,19] possessing appropriate chemical and physical properties. It was demonstrated that metals [20,21] and some organic [22] and organometallic [23][24][25] molecules result in n-doping of SWCNTs, whereas metal halogenides [26][27][28][29][30][31][32][33] lead to p-doping of nanotubes.…”

“…In the literature, there are reports on the studies of the electronic properties of SWCNTs filled with halogenides of 3d-(Mn, Fe, Co, Ni, Zn, Cu), 4d-(Ag, Cd), 5d-(Hg), and 4f-metals (Tb, Pr, Tm). [11,[26][27][28][29][30][31][32][33] The valuable experimental data on the modification of the electronic properties of SWCNTs due to the filling were obtained. Signatures of p-doping were investigated by optical, Raman, and X-ray photoelectron spectroscopy (XPS).…”

Single‐walled carbon nanotubes (SWCNTs) with a mean diameter of 1.4 nm are filled with rubidium iodide. The filling of nanotubes is proved by high‐resolution scanning transmission electron microscopy. The chemical composition of the filler is confirmed by X‐ray photoelectron spectroscopy (XPS). The electronic properties of the filled SWCNTs are studied by XPS and Raman spectroscopy. The encapsulated salt leads to n‐doping of nanotubes. The detailed multifrequency Raman spectroscopy investigation of the alteration of Raman modes of SWCNTs upon filling is conducted. The doping‐induced changes in the radial breathing mode and G‐band are revealed. It is found that these changes differ for the metallic and semiconducting SWCNTs. The obtained data and revealed trends are expected to be helpful for forthcoming studies to interpret the observed changes in Raman spectra of filled metallic and semiconducting SWCNTs.
