“…Well-established methods to produce graphene include micromechanical cleaving, solution-phase exfoliation from graphite, , chemical vapor deposition (CVD), − and organic synthesis-based methods. , Micromechanical cleaving technique, also known as the “Scotch tape” or peel-off method, tends to produce graphene with the best quality and the least amount of structural and compositional defects . However, this method offers only limited control over the number of mechanically peeled-off layers, and it is not suitable for mass manufacturing of graphene.…”

Electrically−transduced sensors, with their simplicity and compatibility with standard electronic technologies, produce signals that can be efficiently acquired, processed, stored, and analyzed. Two dimensional (2D) nanomaterials, including graphene, phosphorene (BP), transition metal dichalcogenides (TMDCs), and others, have proven to be attractive for the fabrication of high−performance electricallytransduced chemical sensors due to their remarkable electronic and physical properties originating from their 2D structure. This review highlights the advances in electricallytransduced chemical sensing that rely on 2D materials. The structural components of such sensors are described, and the underlying operating principles for different types of architectures are discussed. The structural features, electronic properties, and surface chemistry of 2D nanostructures that dictate their sensing performance are reviewed. Key advances in the application of 2D materials, from both a historical and analytical perspective, are summarized for four different groups of analytes: gases, volatile compounds, ions, and biomolecules. The sensing performance is discussed in the context of the molecular design, structure−property relationships, and device fabrication technology. The outlook of challenges and opportunities for 2D nanomaterials for the future development of electrically-transduced sensors is also presented.

“…In recent years, the interest in nanographene chemistry has produced a range of extended π-conjugated systems, many of which contain heterocyclic rings. Recent advances in nanographene synthesis were reviewed by Yan and Li, Tran-Van and Wegner, Wu and co-workers, and the Müllen group . An account of the chemistry of contorted polycyclic aromatics was published by Nuckolls and co-workers .…”

Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic nanographenes) are a highly versatile class of organic materials, applicable as functional chromophores and organic semiconductors. In this Review, we discuss the rich chemistry of large heteroaromatics, focusing on their synthesis, electronic properties, and applications in materials science. This Review summarizes the historical development and current state of the art in this rapidly expanding field of research, which has become one of the key exploration areas of modern heterocyclic chemistry.

“…Indeed, this would be the first three dimensional hexabenzocoronene (HBC) molecule. HBCs are interesting because of their supramolecular behavior and electronical properties [ 46 – 48 ]. However, the cyclodehydrogenation reaction on this molecule proved to be quite challenging due to ring strain and led to a complex mixture of partially dehydrogenated and chlorinated products.…”

SummaryThe research of cycloparaphenylenes (CPPs), the smallest armchair carbon nanotube, has been a quest for the past decades which experienced a revival in 2008 when the first synthesis was achieved. Since then CPPs with various ring sizes have been realized. The incorporation of substituents and the synthesis of CPPs with building blocks different from phenyl rings bear challenges of their own. Such structures, however, are highly interesting, as they allow for an incorporation of CPPs as defined nano-objects for other applications. Therefore, this review provides a status report about the current efforts in synthesizing CPPs beyond the parent unsubstituted oligo-phenylene structure.
