Supramolecular Chemistry on Surfaces 2D Networks and 2D Structures Explore the cutting-edge in 2D chemistry on surfaces and its applications In Supramolecular Chemistry on Surfaces: 2D Networks and 2D Structures, expert chemist Neil R. Champness delivers a comprehensive overview of the rapidly developing field of two-dimensional supramolecular chemistry on surfaces. The book offers explorations of the state-of-the-art in the discipline and demonstrates the potential of the latest advances and the challenges faced by researchers in different areas. The editor includes contributions from leading researchers that address new spectroscopic methods which allow for investigations at a sub-molecular level, opening up new areas of understanding in the field. Included resources also discuss important supramolecular strategies, like hydrogen-bonding, van der Waals interactions, metal-ligand coordination, multicomponent assembly, and more. The book also provides: A thorough introduction to two-dimensional supramolecular chemistry on surfaces Comprehensive explorations of the characterization and interpretation of on-surface chemical reactions studied by ultra-high resolution scanning probe microscopy Practical discussions of complexity in two-dimensional multicomponent assembly, including explorations of coordination bonds and quasicrystalline structures In-depth examinations of covalently bonded organic structures via on-surface synthesis Perfect for polymer chemists, spectroscopists, and materials scientists, Supramolecular Chemistry on Surfaces: 2D Networks and 2D Structures will also earn a place in the libraries of physical and surface chemists, as well as surface physicists.
