Molecular Nanographenes

This book aims to overview the variety of nanographenes. Their diverse morphologies, mostly stemming from their structural defects, different approaches of synthesis, their singular chiroptical and photophysical properties and potential applications are covered in this book. Includes both top-down approach where nanographenes are obtained from graphite by fragmentation of pristine graphene by chemical methods, leading to non-homogeneous NGs (flakes) without control of their size and shape and bottom down approach is using standard synthetic chemical protocols resulting in homogeneous and well-defined discrete molecules with a full control on their size and shape.

Professor Martín has authored over 600 scientific publications and has received numerous scientific awards, including the Alexander von Humboldt award in 2012 and the Spanish National Prize in Chemistry in 2020. His research interests span a range of targets with emphasis on the chemistry of carbon nanostructures such as fullerenes, carbon nanotubes, graphene and nanographenes. He is a member of the Academy of Sciences of Spain and the Royal Academy of Doctors of Spain, Member of the Europaea Academy, Fellow of the RSC and member of the ChemPubSoc Europe Fellow (now Chemistry Europe Fellow). He has been the recipient of an Advanced Grant (ERC) and a recent Synergy Grant (ERC) currently under development.

Colin Nuckolls joined the faculty at Columbia University in 2000, was promoted to the rank of Full Professor in 2006, was the Chairman of the Department from 2008-2011. Since 2016 Nuckolls has been the Sheldon and Dorothea Professor of Materials Science. He is the exective editor for ACS Publications journal, NanoLetters. His research, at the intersection of organic chemistry, materials science, and nanoscience, is directed toward the synthesis of new types of electronic materials and uniquely functioning devices, goals he is working to achieve by combining the synthesis of new molecular species, state of the art lithography, unique reaction chemistry, and unusual modes of self-assembly. He is a member of the American Academy of Arts and Sciences.

Klappentext

Explore the world's most powerful materials with nanographene research Graphene, comprised of a single layer of carbon atoms in a honeycomb nanostructural arrangement, is the thinnest and strongest material yet known to science. Despite that this pristine carbon allotrope exhibits a variety of outstanding properties, its zero bandgap prevents its use for some optoelectronic applications. Fragments of graphene, or nanographenes, have shown a great potential to obviate these problems, thus paving the way for the development of chiroptical and optoelectronic properties. Molecular Nanographenes constitutes a comprehensive overview on the synthesis of these materials and their properties. Covering their widely varying morphologies, their potential applications, and their valuable chiroptical and photophysical features, it also analyzes multiple approaches to obtain nanographene by using both top-down and bottom-up methodologies. The result is a one-stop shop for materials scientists and other researchers interested in these emergent and fascinating materials. Molecular Nanographenes readers will also find:

• A careful distinction between top-down and bottom-up approaches to nanographene synthesis
• Detailed discussion of nanographene configurations including planar, bilayer, helical, nanobelt, and many other geometries

• An authorial team with pioneering research experience in the study of nano-sized graphenes and their synthesis Molecular Nanographenes is ideal for materials scientists, polymer chemists, solid state chemists, organic chemists, and any other researchers looking to work with shape and size-controlled flakes of graphenes.
