“…Alternate assemblies of C 60 -ethylenediamine adducts have been formed on the surface using a repeating immersion process of substrates into solutions of C 60 and ethylenediamine ( Figure 11). 54,55 The principals of formation of alternate assemblies of C 60 -ethylenediamine adducts are the same as previously described for the double layer of C 60 systems using C 60 and ethylenediamine. First, gold or quartz surfaces were modified by aminoethanethiol or aminopropyltrimethoxysilane to form amino groups.…”

Fullerenes are attractive spherical aromatic molecules with good electron acceptor capabilities and good utility as an ntype organic semiconductor. By using a fullerene-amine addition reaction, it was possible to fabricate ultrathin-film assemblies of fullerene on the surface of substrates, which were confirmed by photoelectric conversion applications. Addition reactions between fullerenes and primary aliphatic diamines can also occur to form insoluble adduct particles consisting of fullerenes and diamines. In one example, C 60-ethylenediamine adduct particles can be solubilized by addition of alkylacid chloride to residual amino groups of the adducts. Spin-coated or dip-coated thin-films of C 60-ethylenediamine adducts from their solutions are useful as n-type organic semiconductors which was confirmed with solar cell application. In this account, the history of the fabrication and application of fullerene thin-film assemblies and fullerene-diamine adducts using the fullerene-amine addition reaction is introduced and summarized from the early studies to more recent developments.

“…To create such applications, extensive studies have been carried out to obtain fullerene thin films with two‐ and three‐dimensionally ordered structures. Distinct methodologies have been used to form epitaxial films, such as Langmuir–Blodgett films, chemically self‐assembled films, and sol–gel films . The layer‐by‐layer (LbL) assembly technique, which was originally reported by Iler in the 1960s, has been improved to be a versatile and powerful technique for fabricating layered thin films with precise control of the film thickness and composition .…”

The layer-by-layer self-assembly technique was used to fabricate a series of multilayer thin films with poly[4 0 -(4-methacryloyphenyl)-2,2 0 :6 0 ,2 00 -terpyridine] (PmPhtpy), polycyanofullerenes, and transition metals (Ni 21 and Co 21 ). The polymer PmPhtpy was prepared by free-radical polymerization, and this was confirmed by Fourier transform infrared (FTIR) and 1 H-NMR spectroscopy.The polycyanofullerenes, which were characterized by FTIR, ultraviolet-visible (UV-vis), and 13 C-NMR spectroscopy, was synthesized via the bromination of fullerene and then substitution with a nucleophilic reagent [potassium cyanide (KCN)]. The optical properties of the films were measured by attenuated total reflection infrared and UV-vis spectroscopy, and the results indicate that the driving force of the fabrication of the multilayer film was the coordination interaction. The magnetic behavior was examined as a function of the magnetic field strength at 5 K and the temperature (5-300 K). The magnetic hysteresis loops of the films showed a typical S shape at 5 K; this suggested soft ferromagnetic properties.

Functionalized fullerene nanostructures are a distinct class of materials that exhibit the combined properties of both fullerene and nanostructures including excellent optoelectronic features, modified band edges, high electron affinity, fast charge transfer capabilities, and tunable structural and textural properties. These fascinating properties allow for their utilization in many applications such as polymer solar cells, photovoltaics, photocatalysis, photodynamic therapy, electrocatalysis, environmental remediation, and drug and gene delivery. Numerous synthesis methods and anchoring groups are employed for functionalized fullerenes with nanostructures by using convergent bottom-up and top-down strategies. The supramolecular self-assembly and functionalization of fullerenes through robust chemistry approaches such as surface oxidation, grafting, polymer coating, doping of metals/nonmetal heteroatoms, noncovalent modification with 2D materials and nanoparticle attachment result in achieving fine control over its surface and bulk properties, including increased solubility, wettability, electron transport, acid-base properties, adsorption, electronic conductivity, and light absorption. This review analyzes the salient developments in the fabrication of nanostructured fullerenes and their functionalized derivatives for many applications including adsorption, catalysis, sensors, energy storage, solar cells, drug delivery, magnetic and superconducting devices. The contents of this review will allow the readers to cherish exciting possibilities and opportunities in field of functionalized nanofullerenes.
