“…Hence, the ionization of C 60 vapor is facilitated inside the microcavities as compared to the direct sublimation from the surface. Indeed, we have previously shown that during the quasi-stationary deposition, the products of fullerite C 60 EBD contain few mass percent of positive fullerene ions with the energy of up to ≈ 7 eV [13] that strongly influence the coating structure.…”

“…The effective mass thickness of the coating deposited on the substrate was monitored by a quartz crystal microbalance (QCM). To recalculate the obtained data into the geometrical thickness, the mass density of the deposited material was chosen to be equal to the mass density of fullerite C 60 (1720 kg/m 3 ) as no micro-size pores or defects were found in the deposited films using the atomic-force microscopy measurement [13].…”

“…The coating is deposited onto a substrate from the volatile sublimation products typically containing neutral and excited molecules, ions and radicals. It was shown that the coatings produced by EBD of fullerite C 60 contain C 60 polymeric forms [13]. In this report, we concentrate on the analysis of the kinetics of fullerite C 60 EBD.…”

Electron-beam dispersion of pressed fullerite C 60 targets in vacuum leads to the deposition of thin films containing polymeric forms of C 60 . The aim of the present report is to analyze physical-chemical processes in the fullerite target during its electronbeam dispersion through the analysis of the kinetics of the radiation temperature of the target surface, the coating growth rate and the density of negative current on the substrate. It was shown that the induction stage of the process is determined by the negative charging and radiation-induced modification and heating of the target. The transitional stage is characterized by nonstationary sublimation of the target material through the pores in the modified surface layer and release of the accumulated negative charge. Stabilization of the process parameters owing to the convection cooling of the target by the sublimation products and the decrease in the pressure inside the microcavities beneath the pores leads to a quasi-stationary stage of target sublimation and deposition of a coating containing polymeric forms of C 60 .

“…Homopolymers contain fullerene moieties linked to one another via [2+2] cycloaddition to form a polymeric network. This cycloaddition is induced by excitation with photons, [47,[115][116][117] electrons, [48,[118][119][120] plasma discharge, [121] or the application of a high hydrostatic pressure. [50,[122][123][124] Fullerene homopolymers have also been observed in the ambient temperature phases of alkali metal fullerides.…”

structure, which can be easily covalently modified. Progress in extensive organic chemistry of fullerene development facilitates the production of a variety of fullerene derivatives with different structures and physicochemical properties. Additionally, the polyhedral structure of fullerenes containing a large number of bonding sites provides an opportunity for a wide range of covalent modifications. Polymeric structures containing fullerene moieties represent a particularly large class of materials in terms of their number, composition, structure, morphology, and physicochemical properties. [24-29] Some of the most common structures of these polymeric materials are schematically shown in Figure 1. The simplest and most common structures are composites formed from the polymeric chains and fullerenes. Fullerenes form a crystalline phase in the polymeric matrix [30] or are incorporated as guest molecules into polymeric chain containing host moieties. [31] In both cases, covalent interactions are not formed between fullerenes and the polymeric network. However, van der Waals and electrostatic interactions, as well as possible charge transfer between both components of the composite significantly modulate the electronic structure of the polymer/fullerene interphase. [32,33] A stronger electronic interaction between the polymer component and fullerene moieties is expected for the system in which carbon cages are covalently bound to the polymeric chain or covalently incorporated into the polymeric backbone. In the case of in-chain structures, fullerene moieties are separated by short organic conjugated linkers, [34-37] small inorganic linkers, [37-39] or metal atoms and metal complexes. [7,8,29,40-42] A large group of fullerene-based materials consists of organic conducting polymers containing fullerenes attached covalently to the polymer chain by the linker. [43-46] The physicochemical properties of these materials depend on the polymer chain, linker structures, and the density of fullerene moieties within the polymeric material. Similar to olefins, fullerene form homopolymers through [2+2] cycloaddition. [47-51] Fullerene homopolymers, in-chain and side chain fullerene polymers can be cross-linked to form 3D polymeric structures. A large number of reactive π-bond centers in the fullerene moiety enable the formation of star-shaped macromolecular systems with polymeric chains covalently grafted to the C 60. [52-57] In common structures, the number of linked This article provides a comprehensive review of research related to the formation and electrochemical properties of fullerene-based conducting polymeric materials. The paper begins with an overview of composites containing fullerenes incorporated into the network of a conducting polymer through van der Walls, electrostatic, or guest-host interactions. The properties of these composites are generally a superposition of the properties of the individual components. More attention is devoted to the structures in which fullerene is covalently incorporated into the polyme...

A solution of fullerene C 60 in N-methylpyrrolidone (NMP) presents a suitable system for tunable size. However, a mechanism of interaction of a polar NMP solvent with the fullerene molecules is still elusive. Herein, we present the laser desorption/ionization mass spectra (LDI MS) of the precipitates produced from C 60 /NMP solutions of different age in comparison with the typical spectra of C 60 crystallized from toluene and benzene. The distinctive characteristics of the C 60 /NMP mass spectra were identified and carefully examined. The number of characteristic peaks and their relative intensities in the spectra strongly depends on the age of the initial C 60 /NMP solutions. This effect was attributed to the specific C 60-NMP interactions in the solution, namely to the formation of the chargetransfer complexes of C 60 with NMP molecules followed by the fullerene cluster formation. The results of additional measurements carried out by means of Small-angle X-ray scattering (SAXS), Nuclear magnetic resonance (NMR), UV-Vis adsorption spectroscopy together with the Density functional theory (DFT) calculations were in accord with the proposed hypothesis.
