“…56,[101][102][103]111,112 Graphene molecules with seven-or eight-membered rings As two-dimensionally confined structures of graphene, nanographenes, in principle, consist of only six-membered rings. PAHs with five-membered rings have been extensively synthesized and investigated as fullerene fragments and their derivatives following the pioneering works by Scott et al 44,[54][55][56][57]102,118 However, there are only scarce examples of graphene molecules containing seven-or eightmembered rings. [113][114][115][116][117] Therefore, extended PAHs containing non-six-membered rings can indeed be considered as graphene molecules, which allow model studies of ''defective'' graphene and may also find applications in (opto-)electronics.…”

New advances in nanographene chemistry

Nanographenes, or extended polycyclic aromatic hydrocarbons, have been attracting renewed and more widespread attention since the first experimental demonstration of graphene in 2004. However, the atomically precise fabrication of nanographenes has thus far been achieved only through synthetic organic chemistry. The precise synthesis of quasi-zero-dimensional nanographenes, i.e. graphene molecules, has witnessed rapid developments over the past few years, and these developments can be summarized in four categories: (1) non-conventional methods, (2) structures incorporating seven- or eight-membered rings, (3) selective heteroatom doping, and (4) direct edge functionalization. On the other hand, one-dimensional extension of the graphene molecules leads to the formation of graphene nanoribbons (GNRs) with high aspect ratios. The synthesis of structurally well-defined GNRs has been achieved by extending nanographene synthesis to longitudinally extended polymeric systems. Access to GNRs thus becomes possible through the solution-mediated or surface-assisted cyclodehydrogenation, or "graphitization," of tailor-made polyphenylene precursors. In this review, we describe recent progress in the "bottom-up" chemical syntheses of structurally well-defined nanographenes, namely graphene molecules and GNRs.

Synthesis of Nitrogen‐Containing Rubicene and Tetrabenzopentacene Derivatives

et al. 2016

Carbon-based materials, such as acenes, fullerenes, and graphene nanoribbons, are viewed as the potential successors to silicon in the next generation of electronics. Although a number of methodologies provide access to these materials' all-carbon variants, relatively fewer strategies readily furnish their nitrogen-doped analogues. Herein, we report the rational design, preparation, and characterization of nitrogen-containing rubicenes and tetrabenzopentacenes, which can be viewed either as acene derivatives or as molecular fragments of fullerenes and graphene nanoribbons. The reported findings may prove valuable for the development of electron transporting organic semiconductors and for the eventual construction of larger carbonaceous systems.
