“…When considering the functionalization of graphene there are two main approaches to achieve this goal described in the literature. First strategy is based on various non-covalent methods that allow to modify graphene surface (Georgakilas et al 2016;Zhao et al 2021). For this purpose, molecules with planar conjugated π-systems are usually chosen due to their van der Waals, electrostatic or π-π stacking interactions with graphene surface.…”

Graphene functionalized with dianthracene malonate was synthesized and used subsequently for construction of covalently bound graphene-fullerene hybrid nanomaterials. For this purpose, novel approach of Diels–Alder reaction of C60/C70 fullerene cores with anthracene moieties previously introduced onto graphene surface was successfully employed. Structure and composition of obtained graphene and its derivatives were characterized using scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and FT-IR spectroscopy. Obtained results revealed that both C60 and C70 fullerenes were found to be capable of formation desired Diels–Alder adducts, yielding products of different morphology. Capacitive properties of the synthesized energy storage nanomaterials were determined by means of cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) measurements, revealing that functionalization of graphene with C60 moieties enhances its energy storage properties.

“…The noncovalent interaction between amine anchor of SAMs and SLG allows reversible adsorption and desorption for self‐repair, leading to closed packed monolayers without chemical contact on SLG. [ 144 , 145 , 146 , 147 ] Owing to the inevitable water treatment and handling of sample in air conditions, the large‐area graphene synthesized by the chemical vapor deposition (CVD) method tends to be p‐type doped compared to exfoliated graphene (Figure 9b ). [ 148 ] However, when the n‐alkylamines SAMs were treated on the SLG, the G peak position in the Raman spectra was blueshifted with respect to the position of pristine SLG (Figure 9b ).…”

Molecular electronics that can produce functional electronic circuits using a single molecule or molecular ensemble remains an attractive research field because it not only represents an essential step toward realizing ultimate electronic device scaling but may also expand our understanding of the intrinsic quantum transports at the molecular level. Recently, in order to overcome the difficulties inherent in the conventional approach to studying molecular electronics and developing functional device applications, this field has attempted to diversify the electrical characteristics and device architectures using various types of heterogeneous structures in molecular junctions. This review summarizes recent efforts devoted to functional devices with molecular heterostructures. Diverse molecules and materials can be combined and incorporated in such two-and three-terminal heterojunction structures, to achieve desirable electronic functionalities. The heterojunction structures, charge transport mechanisms, and possible strategies for implementing electronic functions using various hetero unit materials are presented sequentially. In addition, the applicability and merits of molecular heterojunction structures, as well as the anticipated challenges associated with their implementation in device applications are discussed and summarized. This review will contribute to a deeper understanding of charge transport through molecular heterojunction, and it may pave the way toward desirable electronic functionalities in molecular electronics applications.

“…In this study, it was shaped into a cone-shaped tip, and the tip retained its shape due to the formation of a ∼0.7 nm native oxide outer shell (GaOx) upon contact with air. 49,50 It has been proved that this type of tip can contact non-destructively with SAMs4, 8–52 and form Cu/Gr/SAMs/GaOx/EGaIn junction.…”
