“…The calculated bond length between the ring carbon and methyl carbon i.e. C1-C17 and C2-C18 are found to be 1.514 and 1.516 Å, respectively, which are consistent with the values reported in the literature [9]. The methyl group attached with the ring is found to be altered the ideal bond angle of 120°.…”

“…Accordingly the title compound has C-H symmetric and antisymmetric vibrations observed at 3050, 3035, 3000 cm in IR are assigned as C-C in-plane bending vibrations which appears in combination with the CH bending vibrations [18]. The vibrations at 477 and 270 cm -1 are identified as ring deformation vibrations are found in accordance with Pouchaname et al [19]. The C-C-C in plane bending and out-of-plane bending vibrations lies in the frequency region below 1000 cm -1 [20] and in line with this fact frequencies at 937 cm ) but the methyl C-H stretching occurs at lower frequency than this [21].…”

“…This steric effect, which arises due to the spatial interaction, has greater influence on physical properties, chemical reactivity, geometric size and shape of the molecule [10]. The other bond angles, especially C2-C3-C8, C5-C4-C9, C1-C6-C5, C5-C8-C13 and C4-C9-C12 are 122°, 121.7°, 121.8° and 121.3° respectively, which are slightly higher than the ideal bond angle, owing to the localized π bonds in poly aromatic hydrocarbon [9].…”

In recent years, there has been remarkable progress in the reduction and functionalization of graphene oxide (GO) using nanoparticles and high-energy optical photons. Most of these reactions are carried out in solutions, whereas the local modification of GO on solid substrates still remains a challenge. In this work, we demonstrate the local reduction of GO and its further destruction, leading to the synthesis of polyaromatic hydrocarbons (PAHs) stimulated by localized surface plasmons (LSPs). The reduction of GO and the synthesis of PAHs have been carried out on a substrate designed for surface-enhanced Raman spectroscopy (SERS). We found that LSPs initiate the destruction of water molecules entrapped in the nanogaps between silver nanoparticles after the deposition of GO from the aqueous suspension. It was demonstrated that OH radicals, as a result of water decomposition, initiate the reduction of GO, leading to the synthesis of PAHs. The reactions have been observed in real time by using SERS. The measurement of current-voltage (I-V) characteristics through conductive atomic force microscopy (AFM), recorded in an LSP-stimulated area, have shown the increased electrical conductivity (more than ten times) compared with the conductivity of GO. The synthesis of new compounds in the LSP-stimulated area has been confirmed by the appearance of new peaks in the Raman spectra and nonlinear I-V characteristics typical for PAHs. We show that the used method allows the local modification of electrical properties of GO and controlled nanopattering of organic compounds on the surface.

The scientific community is actively engaged in the development of innovative nanomaterials with broad‐spectrum virucidal properties, particularly those capable of producing reactive oxygen species (ROS), to combat upcoming pandemics effectively. The generation of ROS capable of inhibiting viral activity on high‐touch surfaces can prove an effective means of reducing pathogenic and viral infections, while avoiding the exacerbation of antibiotic resistance resulting from the extensive use of chemical disinfectants. Carbon dots (C‐dots), in particular, are a class of nanomaterials that under specific conditions is able to generate reactive species. They are, therefore, excellent candidates for fabricating light‐activated functional antiviral devices. Pro‐oxidant C‐dots have been developed via microwave synthesis using an amino acid, glycine (Gly), and 1,5‐diaminonaphtalene (DAN) as precursors. The formation of C‐dots has been obtained by reacting the precursors in microwave using two different acid catalysts, H3BO3 or HCl. The HCl catalyst promotes the formation of a copolymer while using H3BO3 the precursors preferentially self‐condense. The boron‐catalyzed samples have shown to contain radical centers whose intensity increases upon illumination by UV and also visible light. They also show the capability of generating singlet oxygen through energy transfer to oxygen molecules when irradiated. The C‐dots exhibit effective virucidal activity and have been tested in vitro using two different variants of SARS‐CoV‐2, the original strain, and Omicron. Antiviral C‐dots have been finally used to functionalize a model surface, inducing a strong virucidal activity against the SARS‐CoV‐2 coronavirus with both ultraviolet (UV) and visible (VL) light.
