Graphene ranks highly as a possible material for future high-speed and flexible electronics. Current fabrication routes, which rely on metal substrates, require post-synthesis transfer of the graphene onto a Si wafer, or in the case of epitaxial growth on SiC, temperatures above 1000 degrees C are required. Both the handling difficulty and high temperatures are not best suited to present day si...

The polymer matrix with introduced carbon-based nanofiber displays fascinating properties. They have inspired extensive research on the synthesis of polymer composites, which have been applied in catalysis, electronics, and energy storage. In this report, we reported a facile and efficient method to prepare poly(p-phenylene benzobisoxazole) (PBO)/nanographene (PNG) composites fibers via in-situ...

In a nanographene ring with zigzag edges, the spin-polarized state and the charge-polarized state are stabilized by the on-site and the nearest neighbor Coulomb repulsions, U and V , respectively, within the extended Hubbard model under the mean field approximation. In a Möbius strip of the nanographene with a zigzag edge, U stabilizes two magnetic states, the domain wall state and the helical ...

A new disc-shaped highly symmetric C54H20 nanographene fragment, tetrabenzocircumpyrene, has been synthesized and characterized by scanning tunnelling microscopy, demonstrating the potential of this technique for identifying highly insoluble graphenic molecules.

Graphene exhibits unique electronic properties, and its low dimensionality, structural robustness, and high work-function make it very promising as the charge storage media for memory applications. Along with the development of miniaturized and scaled up devices, nanostructured graphene emerges as an ideal material candidate. Here we proposed a novel non-volatile charge trapping memory utilizin...

This thesis reports on the investigation of self-assembled monoand multilayers from nanographene derivatives via scanning tunneling microscopy (STM) at solid-liquid interfaces. Because of the unique electronic properties associated with their π-bonded topology, nanographenes are promising building blocks for molecular and organic electronics, which provide the possibility of tunability together...

Top-down methods produce nanographenes with many carboxy groups on their edges. These functional can be utilized for developing multichromophoric systems. As proof of concept, pyrene is installed the edges by Pd-catalyzed cross-coupling reactions. The lack monomer emissions from functionalized indicates that neighboring chromophores are sufficiently distant to form excimer. pyrene-installed nan...

Graphen. Ryo Sekiya, Takeharu Haino und Shusaku Takahashi berichten in ihrer Zuschrift (e202205514) über die Synthese von Metallnanopartikeln auf lipophilen Nanographenen. Pd-dotierte Nanographene zeigten katalytische Aktivität Suzuki-Miyaura-Kreuzkupplungen.
