Book Description
Organic Chemistry, Volume 22: Catenanes, Rotaxanes, and Knots provides information pertinent to the synthesis of catenanes and rotaxanes. This book discusses the manner of interaction between the molecular subunits in catenanes in the solid, liquid, and gaseous states. Organized into 19 chapters, this volume begins with an overview of the idea of synthesizing molecules composed of separate entities that are mechanically connected to one another. This text then examines the stereochemistry and the other physical and chemical properties related to the mechanical connections in these compounds. Other chapters consider the determination of the absolute configuration of catenanes by extension of the Cahn–Ingold–Prelog rules. This book discusses as well the bond that mechanically connects the catenated rings. The final chapter deals with the model studies of the synthesis of knots, double wound rotaxanes, and higher linear catenanes. This book is a valuable resource for chemists, students, and research workers.

Book Description
This journey through the fascinating world of molecular topology focuses on catenanes, rotaxanes and knots, their synthesis, properties, and applications and the theory of interlocking and interpenetrating molecules. Nearly one hundred years of progress have passed since Willstätter's speculative vision of a molecule consisting of two interlinked rings. But even today the synthesis of such structures are a challenge to the creativity of synthetic chemists. These molecules are not only of academic interest, since they occur naturally. In such molecules as DNA, knots and related topological features play a key role in biochemical processes. In addition, extensive research on the properties of polyrotaxanes and polycatenanes show potential applications as molecular magnets, wires or switches. Twelve international leading experts in the field present the broad and impressive spectrum of the topology of these molecules, from theoretical aspects and new pathways in synthesis to probing their properties. All researchers working in this interdisciplinary area, whether organic, inorganic or polymer chemists, as well as material scientists, will welcome this comprehensive and up-to-date work as an inspiring source for creative research ideas.

Book Description
The construction of catalysts by supramolecular forces has recently become a powerful tool and the role of noncovalent interactions can assist in designing new tools for the construction of effective and selective catalytic systems. It is unquestionably, vastly important to understand how different noncovalent interactions can be controlled or manipulated under appropriate reaction conditions. Supramolecular catalysts have had a tremendous impact on the syntheses of both chemical commodities and fine chemicals over the last 50 years, leading to the discovery of new reactions that were previously deemed impossible. This means that supramolecular chemistry plays a predominant role in accelerating or understanding chemical reactions.This book which addresses the above points is written by some of the leading contributors in this field and is intended for graduate students, researchers and academics working in supramolecular chemistry, organic chemistry, inorganic chemistry, and physical chemistry as well as researchers with an interest in the area of catalysis. The authors give examples illustrating the growth of the field, especially with special emphasis on new results published over the last decade. They also provide an explanation of fundamentals and topical research.

Book Description
Supramolecular Catalysis Provides a timely and detailed overview of the expanding field of supramolecular catalysis The subdiscpline of supramolecular catalysis has expanded in recent years, benefiting from the development of homogeneous catalysis and supramolecular chemistry. Supramolecular catalysis allows chemists to design custom-tailored metal and organic catalysts by devising non-covalent interactions between the various components of the reaction. Edited by two world-renowned researchers, Supramolecular Catalysis: New Directions and Developments summarizes the most significant developments in the dynamic, interdisciplinary field. Contributions from an international panel of more than forty experts address a broad range of topics covering both organic and metal catalysts, including emergent catalysis by self-replicating molecules, switchable catalysis using allosteric effects, supramolecular helical catalysts, and transition metal catalysis in confined spaces. This authoritative and up-to-date volume: Covers ligand-ligand interactions, assembled multi-component catalysts, ligand-substrate interactions, and supramolecular organocatalysis and non-classical interactions Presents recent work on supramolecular catalysis in water, supramolecular allosteric catalysis, and catalysis promoted by discrete cages, capsules, and other confined environments Highlights current research trends and discusses the future of supramolecular catalysis Includes full references and numerous figures, tables, and color illustrations Supramolecular Catalysis: New Directions and Developments is essential reading for catalytic chemists, complex chemists, biochemists, polymer chemists, spectroscopists, and chemists working with organometallics.

Book Description
"The story is told by THE inventor-pioneer-master in the field and is accompanied by amazing illustrations... [it] will become an absolute reference and a best seller in chemistry!" —Alberto Credi "... the great opus on the mechanical bond. A most impressive undertaking!" — Jean-Marie Lehn Congratulations to co-author J. Fraser Stoddart, a 2016 Nobel Laureate in Chemistry. In molecules, the mechanical bond is not shared between atoms—it is a bond that arises when molecular entities become entangled in space. Just as supermolecules are held together by supramolecular interactions, mechanomolecules, such as catenanes and rotaxanes, are maintained by mechanical bonds. This emergent bond endows mechanomolecules with a whole suite of novel properties relating to both form and function. They hold unlimited promise for countless applications, ranging from their presence in molecular devices and electronics to their involvement in remarkably advanced functional materials. The Nature of the Mechanical Bond is a comprehensive review of much of the contemporary literature on the mechanical bond, accessible to newcomers and veterans alike. Topics covered include: Supramolecular, covalent, and statistical approaches to the formation of entanglements that underpin mechanical bonds in molecules and macromolecules Kinetically and thermodynamically controlled strategies for synthesizing mechanomolecules Chemical topology, molecular architectures, polymers, crystals, and materials with mechanical bonds The stereochemistry of the mechanical bond (mechanostereochemistry), including the novel types of dynamic and static isomerism and chirality that emerge in mechanomolecules Artificial molecular switches and machines based on the large-amplitude translational and rotational motions expressed by suitably designed catenanes and rotaxanes. This contemporary and highly interdisciplinary field is summarized in a visually appealing, image-driven format, with more than 800 illustrations covering both fundamental and applied research. The Nature of the Mechanical Bond is a must-read for everyone, from students to experienced researchers, with an interest in chemistry’s latest and most non-canonical bond.

Book Description
This volume includes both asymptotic results on the inevitability of random knotting and linking, and Monte Carlo simulations of knot probability at small lengths. The statistical mechanics and topology of surfaces on the d-dimensional simple cubic lattice are investigated. The energy of knots is studied both analytically and numerically. Vassiliev invariants are investigated and used in random knot simulations. A mutation scheme which leaves the Jones polynomial unaltered is described. Applications include the investigation of RNA secondary structure using Vassiliev invariants, and the direct experimental measurement of DNA knot probability as a function of salt concentration in random cyclization experiments on linear DNA molecules. The papers in this volume reflect the diversity of interest across science and mathematics in this subject, from topology and statistical mechanics to theoretical chemistry and wet-lab molecular biology.
